How to stop me humming

Dear random stranger I saw today:
I hate you
and your bag of spanish oranges,
your red scarf knotted up and round your mouth.

I wish the strings of steam from your nostrils
would add up to a smoke room with no window out.

On your lunchbreak in Luis
choose the blond olives in chili and cumin,
palm a lamb samosa,
as heavy as a collar bone.
Pop it into your pocket.

Eek out the gristle
bring it behind your teeth
chew it like tobacco
and archer at my left eye
as I turn the corner humming.
