Bit of a long winded story and I am probably being silly but my sister called the other day and said Mum had asked us both to chip in on her birthday present and was I ok to do this and how much could I spend. I said yes that was fine and she made some sly remark about how Mum had instructed her not to spend much because I didn't have much money and how this comment had annoyed her since she also didn't have much money. This put me out a bit because my sister has 3 kids and one on the way, her bf does not live with her and she basically lives on support money from the government. And she gets lots of it too for various reasons. So to say that (whilst I agree she probably doesn't have much compared to me) annoyed me because I work bloody hard for my money and should be able to spend it on what I like but instead she was making remarks about how I'd just got a new car etc. I happened to mention this in passing to Mum the next day (how I was a bit annoyed at my sister's comment). I now wish I hadn't. Mum and this particular sister are 3 days apart in birthdays and more alike than they care to admit. Mum is now angry at said sister (in fairness said sister has also managed to annoy several other family members in one week). She has promised not to escalate the situation and I have said to my sister that Mum meant for us BOTH not to spend much. Mum called me this evening and was clearly still annoyed at my sister. I always feel guilty regarding my Mum and so I called her back to ask was she doing anything for her birthday but she seemed still a bit short and curt. I realise a lot of this is my fault I should have kept my big mouth shut but I honestly didn't expect this reaction. I simply had mentioned what my sister said because it had annoyed me and I was sounding out to Mum. Now I wish I'd said nothing and feel that I may have started WW3. I feel like having a cry!
