This shouldn't be difficult bcoz the movie is not that old. So they graduate and are not sure what to do now. The movie is slow and mostly nothing happens. One of them falls in love with a creepy guy that she met in a garage sale. He was selling some old music disks. She might have worked for a short while in a fast food chain too. The girl has short dark squared cut hair. She is a bit short. I remember that the guy had a funny name or old name or something because she made fun of it. After a while she finds herself spending more and more time with this guy. At first she tries to help him hook up with other women. But then she falls for him...
That skinny actor is famous because I have seen him in many other movies.. as for the two girls not that much so.. the general mood is weird and slow and that's what I liked about it... so what's it called?
