This means I take on way too much.
I am in the Indian Dance group at school, and we are practising for a concert next Friday, so we are at it every lunchtime - last week, this week, and next week, getting the dance perfect.
Now the music teacher has asked me to take the choir, as the previous person can't come in during the school day as he is at university. They are singing at the concert on Friday too, so it's not really out of my way, but I really feel underqualified. I mean, I can sightread and sing just fine - I've been in choirs since age 9 - but I can't play a piano part with more than one line, and I've NEVER conducted before! I'm pretty sure that there is a lot more to it than just waving your hands in time.
At least I told her I would only do it this term as a trial.
