OK. Its an interesting start, I like it. But a bit short, maybe? Remember to use full stops, and stick to the past tense (The bells
rings as Joey
walks into the classroom would change to "The bell
rang as Joey
walked into the classroom."
And remember to give your characters depth. Give them feelings, fears, wishes, loves, hates, e.t.c.
I cant wait to see what you'll come up with, good luck!!
