Thank you, Hmoll.
I dont know what i will do, the mother always acts as if we were friends but i want to keep a distance with my pupils. And they will go out from 7 pm to 11pm on a Friday evening, so i also think i have to charge, maybe not like 4 hours teaching but still something.
Of course if a student stays one more hour while i am teaching another one, it is only good (i like when my pupils listen to each otehr) but this time it is different.
