I'm the type who's generally considered the go-to guy when there's a problem, especially when it involve computers or electronics.
I can also usually figure out how to fix just about anything. As I am fond of saying “anything can be fixed, it's just a matter of how much of the original is left when you are done”.
I have a wry sense of humour, which I inherited from my father. Although I usually don't show it until I am fairly comfortable with whom I am talking. Another trait I inherited from my dad is long arms, and large hands.
I enjoy being around kids.
Part of this is that only thing that they really care about, is how fun you are. Which removes a potential source of anxiety.
It is possible that I might not initiate a conversation, because I am quite shy, and I'm also trying to overcome Social Anxiety Disorder.
