[Lucius Cornelius Sulla]

What happens if you lay out the cash for a water trough, and a crow croaks in it too? Is your horse going to insist you send him out water in a glass on a tray?

If I lay out the cash for a new water trough, I will install a crow safety ladder inside to prevent any future critters from croaking! - the troughs are expensive!
