Every year she comes on Christmas Eve and leaves on the 27th, her coming isn't an issue but she literally does nothing for the full 3 days.
For example, yesterday DP the kids and I were going for a walk, asked MIL to come, she refused.
While she's here she doesn't even make a cup of tea, offer to help with cooking, literally sits on the sofa for 3 days.
DP has told her many times to help herself to a drink or asked if she wants to help with cooking or clearing up but she refuses.
DP is about to drive her home, I can't wait to get my house back and get the hoover out.
She's a lovely woman but I hate having her to stay.
Anyone else?
