When does just being friends become restraining order?

I was in the supermarket yesterday and the guy waiting in line in front of me (only buying eggs and bread… scrambled eggs on toast for tea, then?), he had a bit of fluff on his shoulder. I know that I should have just blinked and looked away but I really, really wanted to pluck that bit of fluff off.

I don’t think he’d have appreciated it, though.
