Hmm…
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!
