YANBU, the teacher was in the wrong. She lied. It was not a dress rehearasal or any kind ofehearsal, it was the real thing and what she could hvae said was 'you did a good job under the circumstances.'
I would point this out to the teacher.
Yes, they are human and make mistakes, like the technical music glitch, but lying to the kids isn't fair.
Join if you can't think of anything (at all) to say just don't bother posting.
Completely agree with toastymarshmallow it is really boring and annoying for those who have children who suffer anxiety, are nervous, are very shy or very emotional etc etc to be told this is your fault as a parent and you have encouraged it. Most parents try to do their best for their kids and once we recognize shyness/anxiety/whatever do our best to help our kids and not encourage their 'difficulties'.
Crumbs where are the parental anxieties here?
Ghost it is none of my business but when they are older, 11, 12, 13 upwards they will not (probably) care so much when mum/dad are around, although they may still want to showcase the things they have spent ages working on. Please do not wait until your child has a bigger part in her play, or whatever, to support her by watching her perform.
crashdoll, you do not see what the teacher did? She lied, she told the kids that the performance the OP had taken time off work to see was " a 'dress rehearsal' for the 'real thing' next week," and because of that the child now thinks this is true, which was not the case, so expects her mum to take more time off work to see 'the real thing'.
I am so tired of all the people who keep on coming on to defend teachers all the time. I have always attended all of my kids performances wherever I can, I have supported the school through negative Ofsted, schools fair, change of head, you name it, I was there with cards, or chocolates (as part of a support group) or thank yous (many times). BUT sometimes teachers make mistakes and it is annoying and frustrating and we parents want to talk about it, and maybe see if we are being unreasonable.
Really if teaching is so unpleasant why do teachers do it? Presumably because they get paid and they enjoy it (sometimes). They cannot be off limits for comments, when justified.
