Recently, while my voice was on the fritz, I joked with a neighbor, "I hope no one invites me to a protest tonight. I won't be able to shout any slogans, so I won't be able to do them justice." My neighbor's reply: "They could still give you a sign to carry. So, if you get into a disagreement with someone, you'll have something to hit them with."
Good to know that sinusitis has at least one bright side...
