MIL🤦🏻‍♀️

So today we were at my MILs house. I’m 30+2. It was just me and her in the room and she said “I’m just so excited. I’m available to watch him anytime. Just so you know, just like with Roxy (our dog) there will be different rules at grandmas house and we won’t go by yours. You’ll pick him up and say he’s never coming back here again!” And started laughing. I just sat there like 😐. How would you handle this??
