My daughter is in KS1, likes her teacher and has made good progress. Recently I suspect he's been showing her favouritism, eg. more than her fair share of classroom rewards (to the extent that even my daughter is a bit bemused), highly complementary comments in her reading record etc. Recently, he said to me "can I ask a favour; would you help out on the school trip?" He explained that he has a "list" of what he considers "quality parents" and apparently I'm near the top. (I can't believe a teacher would actually admit to having a list ranking parents according to "quality"!!!) He said "we'd love it if you could come". So no pressure then. He wasn't going to accept "no" for an answer, so I said I'd check what I've got on at work and let him know. I don't think it matters who helps out on the trip and there has never been a shortage of helpers in the past, so what's really going on here? It feels unusual and it's making me uncomfortable.
