MIL did a favour for my sister a while back so my sister bought her a photo frame thinking that she would put a photo of my 2 dc in it. I mentioned once in conversation that although FIL takes hundreds of photos of them non of them were ever on show in a frame. The only ones they had on show were a couple that we had done for them.
Anyway she had dd yesterday for a couple of hours and when I went to pick her up I noticed the photo frame and it had a picture of BIL and his girlfriend in it. I know this probably sounds so trivial but do you think IABU about this. I have told my sister and she is quite annoyed too.
