My mum has been living alone for years.
I have siblings who spend every day with my mum. They are both married to useless bastards - one has had affairs and is a creep; the other works all the time and spends all his free time on the golf course or in the pub - his DC (and my sister) hardly see him. Both sisters seem to hate their husbands but don't seem willing (or able) to do anything about it.
There's me in the middle, quite unremarkable life, but married to someone who treats me well and who I've never had reason to moan about (unlike my sisters, who spend all their time together with my mum slagging off the male population - they do actually seem to enjoy it...). When they visit (and it's usually all of them, since they are velcroed (sp) together), I get snidey remarks about 'Mr & Mrs Perfect' (me & DH), which was funny for about five minutes but now it just gets right on my tits. They also try to goad me into joining in their man-hate-marathons, but I won't.
I work PT, none of them work. My sisters have pre-school aged children & mine are older & all at school, so I very rarely need help with child-care - my mum is usually busy anyway, as she's always either at my sisters houses - she is literally never at home & actually has her own room at one of theirs which she stays in most nights.
Yesterday was a rare occasion where I asked my mum for help - I work flexible hours so can usually work around anything, but I was booked to go on a course for the day and couldn't cancel - and my youngest was too ill to go to school. So I phoned my mum who agreed to come & babysit - all fine.
I came home to find a houseful (of course my sisters had to be there too). Everywhere was a fucking mess - my neices & nephews had pulled all the DCs games out all over the floor & they had clearly had a bit of a buffet all around the house, bits of sausage roll behind the sofa, juice on the floor, soggy bits of rusk on window sills, etc. Nobody made any attempt to clear any of it up. Wierdly there was also a huge bare scratched ugly patch right in the middle of my waxed pine kitchen table. I asked my mum why and she snottily said that one of the DC had spilt their drink and how else was she supposed to clear it up? It honestly looks like it's been sandpapered 
.
What fucks me off is everytime I ask for help, which is rarely, my house is trashed and something wierd happens - like the table incident above. The time before, for example, a couple of months ago (in comparison to my sisters who have Mary fucking Poppins on hand every single day) my mum 'accidently' used stinky bleach to wipe down all my kitchen surfaces - which oozed onto a pile of washing which was ruined and had to be chucked out. The time before one of my neices trashed DC1's bedroom & broke his PSP (he keeps his door shut because he doesn't want them in there - my mum & sisters knows that.
Just realised how long this is - thank you if you've persevered! Anyway, AIBU to expect a little bit of help from my mum every few weeks, when she is honestly on 24 hour duty for my sisters. And AIBU to expect my house not to be trashed in the process? I could have cried last night when I saw my table, and spent all night clearing up their mess after they'd gone. I honestly feel like they try to mess things up for me on purpose - but then I think that would be mad. What the fuck is going on with them???
Am quite miserable about it today, actually
