Speaking of pills

Failure to see/ to recognize is an ongoing problem for the guy with AzD. This morning as I was working here at the computer, Bob came walking in, perplexed, "What is this little thing that was in my pill case?" (I'd already opened the lid on Thursday for him.) I looked at the "small hard white thing" as he described it.
Want to guess?
It was, of all things, a pill!!
Merry, merry!
