"Ah ... lets see," he said, scrunching his face into a ferocious scowl, "Did you finish your homework before you started writing? What do you mean you're planning to do it later? Don't you know that good grades are your future? How are you planning to go to college if you don't get good grades? DON'T GIVE ME THAT LOOK or I'll send you to bed without your supper! And no, you may not stay up until 2 AM writing!"
Sorry ... couldn't resist. I was a teacher for 17 years but I've never been a parent.
And no, if I haven't already scared you off, I'm not a YA mentor. I don't know much about the YA genre having been an elementary teacher.
I'll give you a gold star (rep scale) anyway ...
P.S. Seriously though ... I say this as a former teacher ... do be careful with mentors. There are mentors and there are mentors. If whoever you choose as mentor starts going strange on you - asking about your personal life, wanting a picture of you, wanting to meet etc. break off the on-line relationship.
Although this forum is dedicated to writing, I'm sorry to say that predators are everywhere. Do take care of yourself and report any problem to a parent or legal guardian.
Best wishes!
Mr. Chin
