Connor is your friend who has a slight problem. He tends to pull out his eyelashes due to having a slight trichotillomania disorder. He sometimes tries to hide his face with his bangs, cover his face with his hands when people walk by, and keep his head down.

...

You walk by a corner, holding your books, when you see Connor at his locker, picking at his short eyelashes that have barely grown since the last time he picked at them.
