Age gap too huge??

I am now at my friend's house typing this post. I am bored at his house...all my friends are in their teenage years, screaming and shouting at their top of their lungs. I mean, I am not enjoying myself here. All my friends are still in their secondary school years, underage, playing computer games and shouting for no apparent reasons. Grow up!! Or is it me? Have I grown up too much that I can't mix around with them anymore...

At my friend's house, I feel like I am the one babysitting them instead of hanging out. Perhaps there is a huge age gap between them and me. My notion of hanging out will be sitting at the coffee bar or pub, drinking and chit-chating...that's all. No fuss and worries...
