100 words: Grace

If you say grace and the food sucks, can you take it back? Shouldn’t you wait to see if it’s any good before you thank Him? And if it’s leftovers that've already been prayed over, can you just start eating with reckless abandon, or do you have to pray over the food again? Because that seems pretty shabby if you do. If you chew a piece of gum are you supposed to say grace for that too? Or is it just for things you swallow? If some chick's going down on me, and she swallows, should she say grace first?
