Haha, Actually I get along with my In-law a lot more then I get along with my family haha
Sorry I am not much help, but I can say I do not get along with my brother in law(my sister husband) or his family(other then his parents) and it very very hard spending time with them, they never grew up or something... very crude and rude and so nasty to be around. SO we limit the time we spend over at my sisters, if the whole gang is around
