Hot take, they are not conflicting: you look a gift horse in the stomach.

That's a shower thought if I ever read one.

I like to think that if the free horse was sent by an enemy, I'm well within my rights to slice that sucker in half.

Now, if a friend sent it I'd better just say thanks and give it one of those dog treats that are good for teeth, just to be on the safe side.

Yeah but what if the free horse is a jumbo jet?
