cute, but no reason to blush, really.
You have an oppinion and you have every right to speak your mind. We didn't feel so guilty and want to let you know what we all mean. But on the other hand you also taught everyone a lesson, I guess, not to be too quick in saying "that's easy" - maybe just explain a little more next time...
I already reworded my first attempt lately saying something like:
"Oh! Good that you ask something that is not hard to learn. Once you know the trick this will be really easy!"
my appretice (who is a beginning knitter) beamed at me and said: "So how does it work?"
I think I learned.
