MIL has numerous hospital appointments. Ususally she gets a volunteer car or my SIL takes her. I live 100 miles away and work so it is difficult for me to help.
She has a hospital appointment on a Saturday in a few weeks time. SIL will be away for the weekend on that day, and I have to take dh to airport as he is going to Brussels for a week. Volunteers do not work on Saturday, so SIL suggested she get a taxi and she blew up on her. AI (and SIL)BU in expecting the old cow to take a taxi once in her life? She is mobile and has all her facilties (but is a hypochondriac and suffers from 'nerves'.
