You get into a disagreement/argument.
----
Ian Gallagher-
You and Ian usually disagree on how to handle certain situations; like when a guy hits on you persistently, Ian wants to put the guy in his place, you on the other hand would just like to not cause a scene and let karma do it's job.
Lip Gallagher-
Lip would regularly call you out for staying out late some nights with friends and this makes you upset because it would seem that he doesn't trust you.
Mickey Milkovich-
You and Mickey would fight over little things like him drinking the last of your beer and you trying organise his messy stuff around the house.
