I overheard this conversation today and made me laugh. Mask user: You there! Where’s you mask? Teenager: I am scared to wear one in case I can’t breath.

Mask user: Don’t be stupid. Of course you can breath with the mask on. Fucking idiot. Teenager: So you can breath when the mask is really tight round your mouth?

Mask user: That’s right. No problem. Teenager: Then if the air can get through, how is the mask supposed to stop a virus?

After a few seconds while the mask user contemplates this response the teenager follows up: who’s the fucking idiot now then? And casually walks off ????
