Btw, there's been at least one, maybe two times where it seemed a lot like Tani-san understood what Pun Chan was saying.
Mainly I'm thinking of the time Pun Chan thought Prez was dying and Tani-san came to visit.
Prez: Pun chan's been acting really stressed lately, I wonder why.
Pun chan: Meow meow meow! (I have to make Prez's last days as comfy as possible 😭)
And then Tani-san just "happens" to casually ask about Prez's health.
