You and Tom are dating for 4 years.

You two normally kiss around friends so it's normal but anyway. He was talking to Theodore and Draco and you walk up. When you sit down he pulls you into his lap. He pays NO attention like 100% NO attention to you so decide to mess with him. You kiss him when he's in the middle of a conversation.

Tom: "You're gonna regret that doll" he whispers

(If Tom ignores me like that then it's break up time!)
