First...Just Say NO.

You can call the lady back or not...but if anyone asks for something that I don't want to give/do/say/take on, two letters and you're good to go. No! LOL
If you have a hard time saying it, practice! I stood in front of a mirror (counselor's idea) and looked myself in the eye and said, "No. No. NO! no..." I cried and giggled and learned to say it...then to people next. Hard for me, I was such a Milk Toast in those days!
Now as for the idea of knitted thongs...Ouch! One word for you on that one...
NO!!
