I never liked the idea of Twitter because I'm not one of those people that can explain everything in 140 characters

But since I got a phone for my birthday...I'm wondering......should I join Twitter? Just so I can update my dad about where I am?

Now mind you, I'm not going to tell everyone what I'm going to do 24/7.....cause that's what Blog/Diaries/Journals are for. But I feel a little uneasy about going out alone without telling someone where I am.
...

Makes complete sense to me.
