I am in a WhatsApp group with 3 friends. We send each other cat jokes - cartoon type things that you might find on a birthday card. One of them who I am very close to has been very annoyed with my recently but I don't know why. (I have asked). She sent me a very angry text message last week and has generally given me the cold shoulder. The same person had her elderly cat put to sleep 5 weeks ago, after a long and happy life. She has messaged the group back to say not to send her cat jokes because they are too upsetting and she can't even walk down the cat food aisle in the supermarket without crying.
YABU = sending somebody a cat joke 5 weeks after the death of a cat is insensitive
YANBU = the upset is being used as a stick to beat me with and has more to do with her campaign against me than any genuine inability to cope.
