Remind me why Sports exist?? My bf can NOT hold a civilized, low toned conversation about sports. It's gotten so serious I know exactly who's he's talking to by the way he talks to them. If he's flustered && hot headed it's always his cousins Donneith or Three..when he's mild tempered && relaxed it's his cousin Pooh. He gets so loud, I always prepare for a visit by some cops or he will almost chew his headset to bits when he's talking shxt on the game. I don't get why it's that serious, only if our relationship gave reactions like that😂😂😂😂😂😂😂
