Cancel the cheque OP :)
I'm surprised at how many people don't know what grill means, or thought it was a new term. I knew what it meant from a Nelly song from years and years ago. Every time I come back to the thread I have it going doing round in my head.
I loved the pp who mentioned people getting her kittens grill, Ive got an eleven week old puppy and people are in her grill all the time, even after being asked not to. Most of the time I don't mind, I know she's cute, but sometimes I'm trying to train her, I'll ask people to not try and pet her when I'm calling her to me, to wait until I'm finished and they can fuss over all she wants, most people just wait and watch her and then fuss over her, but the odd one or two think I'm being a "bitch" and keep deliberately trying to make her go to them. Im gonna activate my fuck off shields and see if it helps.
Seriously though OP, YANBU, it's ok to want you own personal space, you don't sound rude or horrible to me, and ignore the arse that wished PND on you for wanting your own space. It may be well intended when people want to fuss your baby, but that doesn't mean you have to oblige and shut up and put up.
If I'd seen you crying I'd ask if you were ok and would follow your lead.
