I'm not old

I just realised that I like talking to people who are older than me more than to people of my age, not to underestimate my friends of my age. Err, not really old though, maybe around 2 or 3 years older. Because... well they are wiser, maturer, and they sure know something I don't know, so it's just good to learn something from them, in a friendly way.

I don't know why, is it because I'm behaving/thinking like an old lady?
