Ex-inlaws & a tricky situation ?

I would bluntly tell them, "You lost your goddamn minds if you think I'm gonna take any s.h.i.t. from you. Here's my rules that we WILL play by: You do the right thing and you see MY kids. You act like a bunch of goddamn idiots and you don't see my kids. Don't f.u.c.k. with me! I will set you straight and think nothing of it!!"
