Hmm…

wildesdaughter:

How does one politely and tactfully tell a very sweet young woman that the fumes from her cat’s litter box are killing me?

Oops, I pressed <enter> and apocalypsed my reply. Shall play again.

Stage a fight with your man in front of the sweet girl.. like so:

A: Uh, D, you did not clean the kitty litter, you evil punk

D: I cleaned it yesterday and put fresh litter in!

A: Oh..

Then look really uncomfortable and make a quick exit :D

p.s. I assume you are Trin’s primary caretaker.. reverse the roles if you wish!
