Your girlfriend has been looking more and more worn down lately. That's why, when she came to you in the middle of working on a project, you became worried. She doesn't want to work on it anymore, and can't find a reason why she would continue to do it. She's burnt out, and needs you as a recharge. Get those endorphins going... right? A short cuddle will do the trick... orrrr a long one. It's a good thing you love eachother.
Decided to just drop this for this week and cook up some other ideas before next week comes...
