She is probably doing that because in your email to her you said I need the payment by Friday night because. Then when she does give you payment on Friday you take longer to deposit the money meaning you didn't really need teh money so you could spend it which is probably what you said in your email so that is what the parent is questioning in a round about way. The reality is you are paid by a certain time and up to you when you deposit it but the money is there for when you decide you need to use it. She is just being petty. IF she wants to go back to transfer let her just change the date and time it is due by.
