This has been happening for as long as I have been with DH.
Several times a week, FIL pops over uninvited and if there is an open door (quite often we leave the back door open) he will make entry into our house. We both WFH and there’s been several instances of him peering through the window, walking into meetings, talking loudly to us whilst we are on work calls.
Other notable examples include when I was in the shower and he came into the house, the next thing I heard him shouting he was coming upstairs!
Then today, we are prepping for DS third birthday. I am out in the garden weeding wearing a t-shirt with no bra, and small shorts, all of a sudden I hear the back gate swing open and he’s stood there - deciding he’s coming to the party 3 hours early! I must have looked cross and he immediately made a point of saying I looked annoyed as I scurried away to put a bra on.
I realise this may be a generational thing of just walking into relatives houses, what would you suggest I do in this situation? AIBU?
DH has tried to tell him in the past but he’s very sensitive and just gets offended. He also doesn’t get the hint to leave either, you basically have to be walking out of the house to leave yourself!
