“Hey Jebster, here is a little piece of advice we use when someone makes an asinine comment about a game after the game ended: look at the scoreboard, end of discussion.”
We have younger relatives attending De La Salle, and they have been told, when a sore loser says something obnoxious during or after the game, to just point at the scoreboard and say nothing and move on.
I did not attend De La Salle, which is a good school and puts out some great teams, but was told the same thing: Scoreboard.
