Ron listened as the female went on about basements and floor drains. Did Ron have experience with basements and floor drains? He went to answer her but she had already turned her back to him and wanted him to follow her.
Nope. Ron thought to himself but instead answered with, "I know a little." Why had he lied? Well, he didn't want to look completely hopeless as a male and how difficult could it honestly be to get rid of some water? It wasn't as if it was Ancient Runes or something.
Every lad should know how to inspect a drain? Ron swallowed hard at that statement. He didn't know a the workings of a drain anymore than he knew the workings of a fish tank. Why did muggles put fish inside a glass cube and watch them swim around in captivity as a form of entertainment?
