My mother, on a day out at Crealy Adventure park with me and my DCs last summer (which she paid for, because she is very generous and adores my kids) said in her loudest voice "My goodness biscuits, there's a family over there with the most ENORMOUS child I've ever seen in a nappy". Said child's older sister was standing right by us at the time. She just has no awareness. It was so embarrassing with sister right there I couldn't even say for heaven's sake mother he may have special needs, or may only be three but just be very tall, so I just had to pretend she hadn't spoken and change the subject.
Same holiday, on receiving the news by phone that one of my parents' oldest friends had died, alone, of drink (my father was visibly quite shocked and distressed) immediately said, see, biscuits, we won't last forever, so make the most of us. She's 67, in rude health apart from a degree of hypochondria, but it's all about her...
If we're planning a visit to them she always phones up beforehand to give me a list of things she thinks I won't remember to bring (like raincoats and wellies for my DC, or food for the journey). How does she think I have made it to age 41 and kept two children alive and well all this time?
She also likes to engage my DP in conversation, goading him with 'lighthearted' barbs' like "Oh, do you find you find it very difficult having to live with my daughter? She is messy, isn't she? She is noisy, isn't she? Full of opinions, isn't she? (ahem)" and just generally trying to sow, or mine for, discord. She would never see that this is what she's doing though.
Sorry, I've gone on a bit too. Mine does not read the Daily mail, in fact she would be snobbish about it; she reads the Times but actually closes her mind to anything except the gardening pages!
