Guitar

I have decided to learn how to play the guitar. My friend Mark is teaching me...much to everyone's annoyance! but i think i have a natural talent. It is like the funnest thing ever, except my fingers don't really agree with me. Pinkie is the worst..randomly strumming, not holding down the string enough...but i shall train him to behave.
Now most of you are probably wondering...who would give that girl a guitar? Well here's what you need to know...Andrea lent me her guitar, and Mark is my sen say (like that mark?...sen say is so much cooler than teacher)
So if you have a complaint about my playing please address those two people.
Here is a sample of what i know so far:
The A cord
The B cord
The C cord (i learned it but i sort of forget it already)
The D cord
I can also play the opening of a No Doubt song.

I also like to write random songs about what i am doing. This guitar thing is awesome...all i need now is a guitar strap, a pick, a case, and to learn how to actually play!
Oh ya, i use a dime as my pick for now. This requires MUCH more talent as it is much smaller and harder to handle than a pick. See, I'm practically an expert already!
I should start thinking of band names...any suggestions?
