Hang over

No...I did not drink..
My "hang over" means the feeling of post DU.
I told Velle, I can still dream about DU, our practices, our steps these days.
Whenever I see my wallpaper-our sch daze group photo, all the moments abt it flash into my mind again.
I can tell every single story when I look at any1 of them.
It is so hard to forget..oops, not to forget..of course, i won't forget..It is just too hard to pull myself out from the DU memory.
However, I have this weird feeling when I accidentally bang into any of the sch daze dancer..
What role should i be??A dance mate that used to perform together?An ex-junior? A friend?
I am confused..
