What a shame!
My first husband has managed to annoy all four of our children simultaneously, usually he only pisses them off one at a time. I'm not really sure what has happened though I do know It was something to do with his birthday.
He has always expected all four of our children to attend him on his birthday along with their children and they are expected to provide expensive gifts. He has always been difficult to buy for and extremely ungrateful, when I organised a microlite flight for him, he complained that one flight wasn't much, he would have preferred a course of six flights! As I was working in our business at this time and he refused to pay me a wage he was lucky he received anything.
Our children rarely tell me anything about him, they know I'm not really interested although I do always ask after his health.
This morning I popped in to see my oldest daughter and she was seething from an email he'd sent her, tomorrow I'm seeing my other daughter so I will no doubt hear more. All I can do is listen sympathetically. I do not make things situation worse when they tell me things, I have no need to, he has managed to upset everyone on his own.
