This is kind of a random subject--but I am doing an informal survey. I think people who stay in the same place forever don't really think much about this--because everyone does the same thing. But, since we move a lot, and we are from different places. . .it is different everywhere we go, and can cause some issues.
Where I grew up, in a very small town, we all knew each other. We called grown ups by their first names. if parents had their children refer to a grown up by "Miz (the Texas version of Mrs. OR Miss) Last Name" it was an indication to that adult that we would not be developing a relationship. It was basically a parent's way to say "We don't know you. We aren't going to know you. You and I will not be friends." without actually saying those words--and maintaining a hospitable, courteous manner (meaning--using the kids to be the mouthpiece!) I don't think it was intentional--it was just that we were such a small community that we were very much like family with most of the people.
In the Army community, it seems very common to use "Miss Firstname." I like it, because it seems respectful, but not formal. some people insist on last names, but it seems so out of place among all of the other kids, that it tends to stick out.
Here, the kids all use Mrs. Lastname. I think it is weird. I know it isn't intended to be standoffish, but it feels that way to me. I don't tell any of the kids to call me by my first name, since I think they should do what their parents prefer, but I really don't like it. I feel like they are more comfortable with me if they can say "Ms. A. . ."
Without realizing my error, when we first got here, I taught my kids "Ms. Firstname" for everyone. As I started to realize that no one here did that. . .I tried to teach the kids differently, but they are little, and the change has been hard. Some of the adults are pretty odd in the way they respond to it as well, but some of the people here are odd about a lot of things.
I kind of thought we should go to using last names unless otherwise invited, but that doesn't work with little kids. They have to learn the first thing you tell them.
Last names are also very hard for them to pronouce sometimes. And, if I don't know the correct pronounciation (that has happened a couple of times) I don't know what to tell them. AND--my kids are better about it now as they get a little older, but all three of them have had trouble knowing the difference between Mr. and Mrs. They either think that whatever last name it is refers to only one person, or they call the man Mrs. and the woman Mr. half the time. It took me a couple of months to figure out that R. thought that one of his friends only had one parent. . .he didn't know that I was talking about two different people with Mr. and Mrs. Then when he met them, he just thought the had the same name, so he would say "Mrs. M--the mom Mrs. M--said I could come to a playdate." Or, "Mrs. M--the dad Mrs. M--he's really tall."
So, basically, I ask adults now what they want my kids to call them. That might not be the best approach--but it works for me. My question is: What do you prefer kids call you? Not the ones that are close close. Like the our kids call the McFamily Aunt S and Uncle G, and their kids do the same for us. I don't mean those kids. And not the kids that are your students at school or whatever. . .just like your kids friends or whatever. What are you most comfortable with and what is normal in your area--wherever you live now?
He also hid the eggs that the kids decorated last night, and we had quite a tough time locating the final egg! Daddy came through and found it when we got back from church! 
I don't know if you've heard of this organization, but they are really cool. They were founded to provide a way for soldiers to get the real message out to the public about what is going on in Iraq. They are real war heroes who are telling their own stories about the GOOD that they've seen with their own eyes and done with their own hands over there. It is amazing. David Bellavia was in our unit in Vilseck. He is up for the Medal of Honor!!! He is a really cool guy, and he is a co founder (I think) of VFF. 
Several guys--Pete Hegseth, Bellavia, and a couple others--spoke. Academy Award Winner John Voight spoke (he's awesome) The kids kept saying "We got our picture taken with Ben's dad!" (from National Treasure!)
and two bands performed. It was so fun! The kids had a great time. They have never been to a concert before and they got to be right up next to the stage. 
We talked to both bands after their performances, and took the kids pictures with them. The guitarist gave N and his buddy P some guitar picks, and I thought they were going to pass out!
