Why am I so nice?

So i just want to say that my teacher decided to recommend that this girl ask me for help on a project for a class. And I'm like ok i'll help. Well i forgot to call her (b/c i was busy working on my homework) and then she emailed me and i felt bad. So at 10:30pm i meet her at the graphic design lab... it is now midnight. MID-FREAKING-NIGHT. Now not that this girl isn't nice. But i have class at 9am. And i have a quiz i'd like to study for. I didn't realize i'd have to walk her through, at the speed of a turtle, on how to use photoshop.. and through TWO assignments?? Seriously. But I just can't be mean; and who knows maybe this Karma thing will actually work for me after this. Now i've taken the class that she's in right now. And she's being way the over achiever. And on my time! I say just draw the stupid ads and you'll do fine (that's what i did and mine were the best in the class, i know as a graphic design minor that is some serious slacking to re-do an ad by hand) but it is also Gill's class. Seriously. I think she's nearly done though. But i want to scream. I want to cry. I want to be at home. I want to be in bed. Not in this stark cold all gray graphic design lab. Oh did i fail to mention i'm still here, sitting next to her? How awful am I to be complaining about someone when they obvliviously sit next to me. :( Don't hate me. I'm trying the best, hey i came out to help. I'm not being mean by saying "that's it, i don't care if you're not done i'm going home." and it's not like i can just leave her here, as a graphic design lab monitor i can't leave people unattended here.... ok i think she's going to print. I'm done. going home now. i hope!
