Hudson's Field Trip

Hudson's Class is going on a field trip in Feb.  We told Hudson he could not go on the field trip if his behavior does not improve at school.  I had to sign his permission but told him he still has not earned his trip.  The next morning he came in the bedroom smiling.  He seemed every proud of himself.  He also had his permission slip form in his hands.  I asked him why.  He said "read it".  Hudson wrote "I sin up"
on the form.  He told me I want to go on the field trip so "I signed up".  Got to love him.  I have to give him credit he almost spelled it all right.
