I'd much rather call someone. I've never been a text kind of person, but with my phone now, texting is pretty simple, so I've been doing it a lot more. I just like to hear a person's voice, the tone in which they respond and all that. I do a lot of talking on the phone (my phone bills are out of this world) so it just is easier for me to talk instead of text.
If its something short, I will text, but if it takes explaining I always call. But if I know the person isn't going to answer the phone or if I'm sitting in class (I know.. tsk tsk tsk), I'll text, or that's a thing of a past for me.
