Today is our DF birthday. I've been away with parents and my DS this weekend. Me and DM put up banners and watched him open cards. He didn't have a card from my Dsis. He received a text from her saying "happy birthday dad, I haven't got you anything yet as you're really hard to buy for". I stood in disbelief she had said this. He was really upset but made out he was ok. Later my DM told me he said I wouldn't have minded if I just had a voucher or even just a card. It's the thought. I feel really sorry for him. I've tried to make a fuss for him today.
My DM text Dsis and said it would have been nice if you just got him a card. Her reply was well he shouldn't be so tough to buy for then, pretty much blaming DF.
I haven't said anything to her and stayed out of it but AIBU to think she's out or order?
For context she was invited along to this weekend away but she declined.
