So your team didn’t make the World Cup. You’re in good company - only 32 of the 195 countries on this planet are playing in the tournament. Historical powers like Italy as well as continental powers like Chile and yes, the United States, are on the outside looking in.
You can lie to yourself and say you’re not going to watch, but we all know you’re still going to follow, just happening to find yourself in the same place when a game is on. Since you’re going to watch anyway, you should pick a team to root for.
