Ok my dad and I have a bit of a history. He's quite odd in his behaviour.
I called up and said we might go up to stay with them just before xmas. They said oh no you can't because your brother is coming then.
I said that was fine but then when I spoke to my brother it turned out he wasn't definitely going then and it might be then or one of four other weekends. I explained that it was the only weekend we could go so given he wasn't bothered about that weekend could we go then.
He said yes and it was all amicable.
Then I called my parents and told them that we were coming up that weekend and had agreed it with db. They flew off the handle saying db is coming then so you can't and weirdly didn't believe me!
Two days later they call again saying you can't come up that weekend as db is coming. I said but I already told you we'd agreed it. They were being totally over the top and ridiculous about it all and getting in a tizz (as they often do).
Why on earth wouldn't they beleive me??! Do they think I've railroaded db/ or I'm too stupid to get this right or something???
