For the typical first grader, I suspect that their birthdays are a bit like weddings.
You look forward to them for at least 364 days.
You invite too many people.
You eat too much cake (read: alcohol for the adult).
You end up with a headache.
You're in bed by 8 p.m.
For the brother of the first-grader (bride), however, especially when you get your first shot at a juice box, the event is a blast!
