The dog thing.

The thing where some random animal comes bounding up to your crotch, sniffs your intimate genitalia profusely and the owners not only let them but actively encourage the act. “Ahh, he’s alright, he likes you! Look!”.

Then, astoundingly, the “do you like dogs?”  question –  which, when politely answered in the neutral, is ignored and thusly the canine sees fit to proceed to slobber/sniff/paw and generally engraciate itself on your personal space.

I do like dogs, don’t get me wrong, but if I came and sniffed your crotch despite your protestations would you be happy?!

You would?

Oh.
