Hope you're feeling better now, tallpoppies - it certainly sounds like you've had a lot on your plate recently.
canella My PIL call me Mami to the DC too, but I'm not sure they'd even be able to pronounce Mummy properly - it is annoying though, isn't it? Especially if they've seen it written down and still write it the German way. I must admit I do have a go at DH if he calls me Mami to the DC, but he remembers to say Mummy most of the time!
I also charged ?10 when I gave a friend of DD1's Nachhilfe in the summer, but that was partly because the DC were around interrupting us during some of the lessons and so I didn't feel I could charge as much as if I was a "professional" English teacher. One of my friends who does teach English professionally charges ?15 an hour for private lessons.
Ernest I'm probably far too late now, but one of the few meals that the DC (and visiting children) are guaranteed to eat is pasta with tomato sauce. Not very imaginative I know, but I've got fed up of spending ages cooking meals they won't eat!
bananas Most of the other parents at school and kindergarten here say du to each other. I would err on the side of caution if I hadn't spoken to someone much before and wait to see if they used du, but if someone has introduced herself to you using her first name, then I think you're pretty safe in using du.
I don't seem to have had a minute to myself since the Semesterferien started. I was planning on spending a couple of mornings at home while DH took the DC skiing, but have ended up going every day apart from Tuesday (when I went to the doctor's about my headache; she wasn't much help, but it does seem to be getting better slowly). The skiing course is going well; it's not very intense compared to the course that DD1 did a couple of years ago, as it's just two hours a day, but DD2 and DS are definitely both far more confident on skis now. There's not much snow around as it's been so warm (13° on the first day!) so the children's ski piste has been covered with artificial snow, but I could hardly tell the difference.
