Don't cry over spilled milk

There really is something to that old saying: "Don't cry over spilled milk".

Spilled milk can be cleaned up. The dog can lick it up. Cows make more milk all the time, so it isn't like squandering a precious natural resource. Sure, if you don't clean it up well, it will smell like rancid milk soon, but that is why you don't waste time being distraught about it and just clean it up.

Now artificially red-dyed instant juice products on the other hand. THOSE are OK to cry about, especially if a quart sized cup of said juice is spilled onto the bookshelf.
