Fart- On each other- around each other- whenever you need to let it out you do.
Give each other the silent reatment- 'Are you mad at me? Hellooooo?!'
Call each other fat- While eating something fattening.
Do silly dances- Usually when you are happy- like when it's the weekend or when you get Chinese food.
Talk about saving- Because you spend money like water as soon as you are paid- on crap.
Talk about one thing and let it lead on to your actual point- 'You need a pension so you will be able to visit your grandkids- you do want kids don't you?!'
You compromise- 'You can impregnate me with two children- but only if you buy me a McDonalds tonight.'
Arrange a night with your friends when you're mad- To give him chance to sit and think about what he's done. Even though he has no idea.
Tell each other when you are mad- Then there is the door slamming.
Apologise- Because you try to never go to bed on an argument.
