I don’t know why, but I have a hunch that Billy listens to Warren Zevon’s Excitable Boy on a loop. When he’s forty-three, he’s still going to be sitting at the kids table, and neither the kids nor the local gendarmerie are going to be too happy about that. If you invite him over, he’s going to eat the cheese ball like an apple. After Billy leaves, you count the spoons, and there are seven more than you started with.
Keep an eye on Billy.
