To change plans on someone

[Lazym]

Hi, this will be short but aibu to be peeved if arrangements are made to go somewhere but then the other person has something else to do or see and wants to arrange for another day. I just think that if you've made arrangements with someone they should stick with them and not expect me to go with it just because they've got something/someone who's more important. They should arrange a different day with the other person or is it just me who's bu?

Hate this! Unless something catastrophic or they are really ill then they honour their original commitment.
This goes along with the 'I'll let you know' response to making plans. Not as in 'let me take a quick check of the diary', it's that they are waiting to see if they feel like it or get a better offer, leaving you hanging.

Depends entirely on the situation tbh. Funeral- YABU, meet up with someone you already see 3 x a week-YANBU.

Yes something like that, obviously it's fine but it was her granddaughter and great granddaughter who she had seen plenty of times lately. Thing is I know she is bulls***g me, i got a message yesterday to say she got her dates mixed up, another this morning to say granddaughter not coming now, can we still go and then another 10 mins later saying granddaughter is coming now, got dates mixed up again. Shes done this to me once before, invited me round, then get a message saying she can't do it and when I see her next she said her daughter wanted to meet with her. Then she's got the cheek to ask me to take her to hospital twenty miles away on sat afternoon but that was done in a sly way as with her first message she only asked me to go with her but once I agreed she then tells me I'm driving her. Feeling a bit mugged off tbh!

You should tell her to ask her DD to take her!

People's situations are different and she may not be telling you the whole story eg my mum is "scared" of my sister due to her mental instability. She would therefore change plans and make things up as she doesn't want everyone to know the truth as it's so ridiculous

Sorry to hear that. I think in my case though this lady just thinks I'll just have to fall in line. I don't really care though as I still went where we was supposed to go anyway and have no intention of going with her now.
