Why do people change?

I've lost a party. Well, I guess it's incredible...Everyone who know me can figure it out.
I don't know, but I don't feel like drinking a lot of bottles of wine, or dancing until my body asks me for resting. I guess I've changed. Unfortunately, I just can't admit that I'll be on this way forever, 'cause future is a surprise box. Do you think that I'm more homeboy because I'm dating? I don't think so. I don't have problems on hanging out with my friends. I could think I'm old and tired, but it's not true! Somewhere in this city there's a bed which tells it if you ask it! (6)
But I can affirm that I'm addicted to my computer...lool My brother went to this same party, so that I can surf the net 'til late today!
Well, that's all, soon I'll come back with something bigger to type here... =)
