Girlfriend forgot her lunch, about to go bring it to her. It's going to seem like I'm doing something really nice, but I wasn't doing anything important anyway. Would rather her not have to inconvenience herself since she's at work
Hey it's a win win! You get the nice points and she gets her lunch! 
Yeah, I was thinking the same thing. I feel a little guilty getting easy credit for something that isn't a big deal, but whatever I can do to help out, I guess.
I bet she loves you for it either way! It doesn't matter how little the effort was, it matters if it was nice!
