Just because someone is the boss does not make them a good trainer, especially if he had an assistant who knew the forms and the system- he may not have made the leap to training you.
I would suggest that when he makes a request of you, that you confirm, by repeating back to him, what he requested and asking for clarification if needed. Also, don't be afraid to ask questions regarding the paperwork....You didn't walk into the job with full knowledge of all their paper.
Basically, you need to train him how to be a trainer. Open communication, courtesy, and your already capable self and you two will be working wonderfully together in no time!!!!
God Bless
