Background: Whole family has been sick except DS (8 months), including my mum who usually looks after DS when I'm at work. I've been off for 2 days and need to go back to work. DH rings his mum to tell her the whole family is sick and to ask her to come down and help look after DS for a day, but after telling her the story she doesn't automatically ask if we need help, instead, launchiing into minute detail about a party she went to on the weekend. DH hangs up in a huff and doesn't bother asking her as "she should have offered if she really cared". I think he should have just come out and asked as she is very much a "it's all about me" person and probably didn't think of it. (Recent example is leaving FIL at the hospital to wait for biopsy
results on his own - she went home to watch Deal or No Deal because she didn't think he needed her there once the testing was completed

(actually turned out to be cancer). Mind you I'm not her greatest fan, but I don't think she should be expected to be a mind reader.
As a result, DH has been a grump all day about his "useless mother". So, who's right? Should MIL have volunteered or should DH have just come straight out and asked her? She lives 1 hr away and had no plans for the day if that makes a difference.
