to not want DP to be at SILs beck and call

[saltdog]

SIL moved into a new house and ever since she's been constantly calling DP to go over and sort/do things out for her. Whenever she rings he drops everything and goes over, tonight she rang because they were was something wrong with the lights, as it turned out she had tripped them and just needed to flick the switch, another common one is that she won't go in the loft because she's scared of falling off the ladder
AIBU to not want DP to constantly go and sort out very minor problems and that he should leave her to do it for herself.

On honesty, I am 30 and wouldn't know how to change a fuse. I think yabu at the mo. If it carried on for years then maybe not.

YANBU!!!!
How old is sister? She sounds VERY spoilt.

My husband has a spoilt baby sister who's recently moved to London (where we live). She's asked for the odd favour since she moved (like store some furniture in our garage etc) and tends to invite herself to stay at ours when her parents visit but nothing like that.

I'm sorry but not going in the loft because she's scared of going up the ladder????? WTH?

There is a difference between 'looking after his sister' and doing everything she asks 24/7. I bet if you asked him to do half the things he does for her, he'd say no to you.

Ninky. Read the OP- it wasn't changing a fuse. It was just switching the fuse back on.

And what was she doing before she had DP doing everything for her? How did she cope with life?

How far does she live though?
I take it the OP and her husband have a family. How convenient is is that every time she calls he had to jump in a car and dash off to help. I'd be a bit put out if it happened at meal/bed/bath time and I was left to do it all while he went over to his sister's house to flick a switch.
