The woman in the office next door to mine clears her throat.
Constantly.
One morning, it seemed like she had something stuck in her throat. This was the first time I noticed it at all. After literally 10 minutes of constant coughing and throat-clearing, I got up and walked next door. We're friendly enough that I feel comfortable saying to her, "It sounds like you have a cough - here, have some hard candies."
But since that time, I've noticed that the periodic throat clearing continues. All day.
It's quiet enough...it's just a little ahem-hem-hem. But it's happened at least five times since I began writing this post. If only it were a drinking game - I'd be well on my way!
