Discrimination

I learnt to ring at 15, with my brother who was 12.  We were in the choir and the tower captain approached us, saying that our parents had
already agreed. My sister was between us in age, and also sang in the choir, but she wasn't included.  I taught her a couple of years later, when the old ringers had stopped coming and we were running the tower. This was 60 years ago so I hope it wouldn't happen today - or would it?
