Welcome to the world of multi-tasking. You have to learn how to think of two things at once. Sounds hard, but after a while, it's a breeze. Just takes practice. After you play for so long, you get to where it doesn't take much of a conscious effort to play most things. I practice on my electric (unplugged) while talking on the phone all the time. Me and my bandmates chat while playing sometimes. Try this to learn how to multi-task. When you can do this, you'll probably be able to talk and play at the same time :)

Choose two sentences of about equal length (in letters), but that don't contain any of the same words. Now, write the first sentence with your left hand and write the second sentence with your right, at the same time. The rule is that one pen can't move unless the other one is moving too. I discovered this neat little trick on my quest for ambidexterity while practicing left handed handwriting.
