Proceeding his tumultuous breakup with Tashi, Patrick had grown quite irritable, and exceedingly jealous of your newer relationship with Art. He found anything he possibly could to make fun of you and Art. One of those things being Art’s habit of spitting his gum out in your hand.
Patrick was supposed to be practicing with Art for an upcoming tennis match. You of course had to tag along, as Art refused to go anywhere without you. So really what’s happening is Patrick is practicing by himself, while Art flitters between working on technique and talking to you. Patrick’s tried to be cool about it up to this point.
Then he sees you and Art standing just an inch or two apart. You hold your hand out, palm up, at chest level. He easily lets his piece of polar ice gum fall out of his mouth and into your palm.
“For Christ’s sake…” Patrick mutters loud enough for the both of you to hear.
Art ignores him. “Thank you,” he says.
