YNNF because yours will get you in trouble with your wife when

YNNF because yours are always breaking your concentration when

YNNF because yours will talk you into doing some dumb shit.

YNNF because yours will burn your house down.

YNNF because yours will drag you down with them

YNNF because yours take revenge too far

YNNF because yours are absolutely no help when you need it the

YNNF if you ever want to have kids.

YNNF because yours will die young when they don't listen to you.
