Bumping it up...I didn't see a similar thread that was recent.
I don't think it's weird to have younger (and older) friends. I don't always have to be with 18 year olds (I'm 18). A lot of my acquaintances are younger and older. It's always fun to talk to people who are age 65+. These seniors have seen a lot of moments in life and can share story after story. I really enjoy those that have lived in the same city most (or all) of their lives. They have seen their town grow up, lived through several Presidents, wars, and other historic events. The number of WWII vets is slowly dwindling down to zero. We need to save those interviews and moments!
One of my good friends is still in high school, a senior (he's 17). I have been friends with him since he was a sophomore, and he's very smart as well...plans on going to possibly an Ivy League college after he graduates!
I like students who have interesting stories to share. Case in point: I have communicated many times with a 7th grader who previously lived in three small, remote Alaska towns before moving to Washington state. I could talk with him for hours about the fishing and the snowmobiling he did up in the AK Bush! Another student (a sophomore) lived in Utah for many years, and has lots of stories to share...not as many as the ex-Alaska student. I also volunteered with elementary students through my junior/senior years. The kids enjoyed all the help I gave them, and some of them still recognize me when they see me.
It's good to have the experience with kids...I plan on getting my Elementary Education BA four years from now.
