Re: Would it bother you if..
Yeah, it would bother me. Who invites themselves for a week to someone else's house, brings a friend without real notice and then just expects everyone there to drop everything and cater to you? Yes, it's sweet that he wants to spend time with his grandbaby, and he should, but the way he's going about it is all wrong.
I'd definitely have your hubby have a talk with him. It's one thing if he asks about all this, but just expecting it to happen is way rude.
