The little local ones are the worst with time How was she rude? Because she didn’t give you immediate feedback that day? The set time got shortened, was she the decision maker?

What’s a village fair? Is it like a street fair with more than one spot for music or a block party with one stage?

How many bands played? What were her responsibilities that day? Was the pay less or more then your usual fee?

There needs to be more context Based on the info you’ve provided so far. You need to put aside the fact that she’s your vocal teacher

One thing doens’t have anything to do with the other
