Don't get me wrong I do love her and she is a good person but her selfishness is unreal sometimes. I know we can all be a bit selfish but she does take the biscuit.
There's stuff from my childhood that made me realise she was selfish. The main being I had a very angry father, he used to hit her. I think he possibly hit me occasionally but it's a bit of a blur tbh? I know he hit my siblings and did so a lot when they were younger. But they were older and left home when I was young. Anyway, dad would come in drunk, and mum would run out and leave me alone with him. I just can't ever forgive that.
She's old now and has a younger dp. They've been together years and have decent social life. I don't blame her at all and think it's great. But she will never stray from her Saturday nights at the club. If anything is ever organised on a Saturday she won't go. Even if I get married she won't come if it spoils her Saturday night out. Tbh I wouldn't really care as I'm not getting married for anyone else, just me and dp and my dss. She wouldn't come to the night do though and I'd be lucky if she came to the day if it would possibly interfere with her Saturday night at the club.
Well I rang her today and she started ranting on about her friend who's changed her birthday party to a Saturday night to suit the grandchildren. Something that would never ever be considered by my mum. Anyway mum won't go even though she's known this friend since she was tiny, and the friend is celebrating her 80th birthday. I asked my mum if the friend was upset, she said 'yes but she's got her family' I said 'Mum I'm just curious but why do you never stray from your Saturday night out, I'm just asking?' She got all huffy and said she likes to go and that's that. I asked again she said she likes to see her friends there. I said but J's your friend? I had to come off the phone in the end as I felt so upset for J 
I know she's old and should do as she pleases but she's always been selfish. She's never offered to babysit. If she ever has it's because we've been absolutely desperate and she's said 'I suppose I could'. That's fair enough but my dcs were the easiest dcs to babysit. My sister would do it and was so shocked how they'd take themselves off to bed and didn't squabble. They're older now and do squabble a bit and I do have to tell them off at times, they're no angels, but have never been any bother with other people. Mum does love them but she has never made much effort with any of her grandchildren or great grandchildren. I don't think being a grandparent makes you a cert for babysitting mind you and should be their choice. It's just her attitude about it.
Dp says I'm the opposite and do anything for anyone but I'm not a mug. I just like to help people and care. I can be an arse at times but would hate to ever be called selfish. I've never called mum this to her face and wouldn't. I do clash with her but that'll never change.
I just can't get over how sad her friend will feel
