Words are confusing. Especially without any context or warning.
I was walking towards the Metro station this afternoon after work, ambling down the middle of the path and keeping a lookout for finches or cardinals or blackbirds or whatever, when suddenly I heard a man call out behind me "Honor eye!"
I had no idea what that meant, but I realized someone was approaching me from behind, and I moved to the side of the path. A jogger ran past and said, "Thanks" as he did.
About three minutes later I realized what he'd actually said was: "On your right."
