Except for this week, of course. Not with a big game on Friday night.
Two close friends will strap up their helmets and compete when King's Minooka team battles with Lancaster and Plainfield East in Southwest Prairie Conference action.
King and Lancaster are in touch nearly every day -- either a call, text, or grabbing a bite to eat. This week, the two haven't exchanged a word.
"Right now, we hate each other," Lancaster joked. "Right after [the game], we'll love each other."
King is hoping to make plans to grab a postgame meal with Lancaster. The only issue, though, is that he can't break the pact of silence with his friend, so he can't extend the invitation.
"We'll finally talk after the game, see what's going on," King said.
Both King and Lancaster are hoping for a potential one-on-one matchup against each other. King primarily plays tackle for Minooka; Lancaster moves around on the defensive line, often working in at defensive end.
While Minooka and Plainfield East are not true rivals, Friday's game has personal meaning; a chance to earn bragging rights. Lancaster has his sights set on beating King for a quarterback sack.
"I'm just hoping to show him what I got because this won't be the last time he sees me," Lancaster said.
King and Lancaster have traveled to each of Northwestern's first two home games together, rooting on the Wildcats along the sidelines then celebrating the win in the locker room.
Each Saturday, during the ride to Evanston, the two talk of the Friday night high school action has come, with each speaking confidently about their respective teams.
"A little trash talking here and there," said King. "We're just talking about our skill players, what kind of talent we have, how the matchup is going to go."
Friday's contest puts a friendly rivalry at stake, with the results sure to be remembered for the next four years and beyond.
