Aahhh I hate these moments when just like that there pops an image in my head and I just CANNOT remember where that image is from.
So this is the only thing I remember, hope someone can help me!

There is this girl standing in a classroom looking out of the window, a boy is leaving. I think she just hurt him, maybe rejected him, but she actually like him very much because she is also hurt so she closes the curtains and cries while she is still holding the curtains. The boy looks back and sees someone squeezing the curtains so he runs back to the classroom.

This is all I know... I know I am doomed
Thanks is advance for the trouble

Yes it is!! You are my life saver! Thanks
