Are you answering your own puzzles now Chris? Is it fun?

Are you answering your own puzzles now Chris? Is it fun?

No. And No respectively.
I didn't answer my own puzzle. The answer to the puzzle as you see (!) it was the solution to a clue in yesterday's crossword puzzle in the Toronto Star. (Okay; I was bored for five minutes ...)
In filling in the clue my mind wandered to another, related word. That gave me the idea for the question, so in a real sense I questioned my answer rather than answering my question.
I hope that answers your questions. (... and never a cross word passed between us ...) ( ... that eye could see)

That part was a bit clandestine to me...
