<human>: Can you provide a brief overview of the text?

Right now I've put myself in a position that's partially my fault. Prom is this Saturday, and my girlfriend wanted to go with our friends to dinner and take pictures with them. Unfortunately, they're all travelling in one big pack in a limousine together and "they don't have any more room for us" despite the fact that we aren't going to be in the limo anyways. That part was partially my fault because I opted out of going with them on the limo because not only has my mother decided to leave my family (she'll be back, I think) last week, but it's also damned expensive at an extra $100 for me. I figured that it would be cheaper and keep our parents at ease if they were able to drive us themselves. Unfortunately, now we are not likely to be able to eat or take pictures with them and my girlfriend is heartbroken over it. 

She's been having a rough week and I want to do something that will cheer her up on prom night. I know you guys don't know her personally, but I'm still looking for suggestions.
