I gave some snark during the dog walk:

Mousy Girl: “Oh god, I can’t believe someone would just tie them up like that!”
Gawky boy: “Yeah, how pathetic and inhumane.”
Mousy Girl: “Too many bad dog owners in the neighborhood…”
Me (coming out of the cafe) : “They’ve been pissing for the past five miles, so they can wait five minutes while I pee for a chance.”
