Couldn't you have taken a packed lunch in? Make a sandwich and take it with you.
I did learn around 7th grade that I could steal his cigarettes and sell them. I guess he did pay for more lunches than I realized, now that I wrote this.
I know from friends in education who see kids come to school who have had to try to find food to bring in. I live in a relatively well off area but kids still come to school with stuff like just dry bread or a single cereal bar as there just isn't anything to hand for them to bring in for school - looking after their kids welfare isn't a given for a sad and sizeable minority.
