I am in a card shop with DDs buying Fathers day cards. I also buy two extra cards for my FIL and sFIL. I won't write and send cards to DHs family as I don't expect him to write and send cards to mine. DH has failed to write and send cards as yet and I am pretty sure it won't get done. He hasn't asked me to sort it out and I haven't offered. I could post the cards but I just think I would be setting a precedent and making a rod for my own back. AIBU?
