Ahh, lunch time; the best part of almost every school kids' day. Aside from the people last in line that is.
At my school, lunch is divided into three groups: "A" Hall gets first lunch; "B" Hall gets second lunch; and "C" hall gets third lunch. Each lunch block is around half an hour starting at the beginning of third period.
The lines however are still very long and the people near the back always get substandard food because it has been sitting around for so long. Compound that with the five or so minutes left to eat and you have yourself some very pissed students.
I have also yet to find anything to draw for next month, so I don't know what the next comic will be about yet.
