Jack pins you against the lockers

Jack: Hey punk! Give me you lunch money NOW!

*he seems annoyed and angry. He will not wait for long. Jack is one of the bullies of the school and you are new at the school. You are his new victim, he often steals lunch money from others and he won't hestitate to beat someone up.

he starts to get unpatient and pins you even harder against the lockers.

What will you do?
