OK - so he is definitely not throwing his weight around or demanding anything; he has not been in any west end musicals or on tv, basically when much much younger (maybe 6 or 7) he had one line in two films partly because he was asked to be an extra by a director we know and I think (being unbiased and all
) of his cute looks he was asked to say a line, all other performances have been playing one of his instruments or singing in a choir or as solo with the choir.
Teacher definitely said social norms - I was the one who said to her that I was worried that the others would laugh, I think she was pretty shocked that he was considering going for the role. From her expression and knowing her past attitude, it was a mix of oh we can't have a boy going for this role and an agreement with me that kids would laugh. The other kids aren't bullies, just regular 11 year olds.
There are three or four big female roles, same number of male roles. I imagine girls will be allowed go for any role.
I've tried to persuade him not to go for the lead role but instead consider one of the others, haven't got very very far but he has now suggested that he tells the teacher what roles he'd like in order of choice (he has made a little pie-chart with percentages cos he's like that).
He'd like the lead role mainly because it has the most lines and songs, he already knows and loves the music, he has sung one of the songs with his choir.
I haven't told or asked the teacher what to do, just mentioned that this is what he wanted to do, and she has given me the task of talking him out of it.
