Aibu to not want to look after DH'S granddaughter, age 8? We have been together for 20 years and I get on ok with his DD, but we are not close & she can be very selfish and ungrateful. I've looked after her in the past, but she is very spoilt and a bit of a brat, so I am reluctant to anymore. My DD is working, so has asked me, but I have said no. Aibu?
