So out down stairs bathroom is on the fritz and BIL was over visiting the kids and needed the bathroom so we said he could use the kids bathroom up the stairs second door to the right of you hit the hot pink door you've gone too far. My DH and I have a master bed room and keep our door closed so there was no reason to even go in there. But lets say he got confused fine but he should have turned around. I went upstairs to get my tablet because my son wants to watch the game but the rest of us were watching a movie so I figured we could all be happy. I open the door to the master bedroom and my BIL is there and he gets startled and drops whats in his hand its my vs lacie (I only have one blue and white one) that I wore yesterday and was in the bathroom hamper. I told him to leave and he did without a word and I told DH what I saw. I'm just like creeped out now but DH doesn't want to tell his parents about it but this Sunday is my sons 12 birthday so his grandparents were taking the whole family to brunch at our usual place. I don't want to go because BIL is going to be there (he's his favorite uncle) but how would it look if a mom wont go to her own kids birthday brunch and honestly I don't even want him around my kids anymore. I'm trying to come up with a logical reason why he had my dirty underwear but honestly I can't. I even threw my Lacie out I don't even want to look at it anymore. I'm just so creeped out.
