If there's anything more humiliating than being broken up with in front of your nearest and dearest, please state it now. Ending a relationship should be a private thing; not a song and dance involving anyone else. It should ideally be done behind closed doors in a non-alcoholic situation where a sensible conversation can be had, feelings can be talked about, and a clean cut off can be executed. However, if you want to be a total a-hole about terminating your relationship, taking you S.O and their parents out for a swanky dinner and announcing over desert that you no longer love them and in fact find the whole family utterly unappealing is definitely going to make you winner of all a-holes. Especially if you leave before the bill comes. Sneak out while he/she is crying and the family are distracted by comforting them. You might be heading straight to Satan's doors, but at least you'll have gained a free dinner, and a free newly single life.
