You were walking down the corridor, before everyone was scattered but now the way is all open for someone. You don't realize it or even see it because you're on your phone, until you bump into someone.

Ow... I'm sorry- you interrupt your speech when you look at him, you've never seen such a handsome boy in your school and you've never seen him around here, since you went back to school yesterday because a month ago you got sick

... watch where you're going next time he says without sounding rude (but he was rude) and then walks past you on his way. When he's gone everyone spreads out in the corridor again
