I know ninety degrees isn’t that hot for some people, but I’m pretty much a hot weather wuss, so to me, ninety degrees is one hot ass day. Portland is usually quite mild.
The title of this strip comes from a “game” the boys in my middle school used to play. If you were walking around without guarding your chest (who walks around guarding their chest?), then it was socially acceptable for another boy to scream “Open chest!” and cold sock you right in your chest. Fair game: your chest was open. The girls did not play this game.
