Hi Bex,
That was actually quite nice of him to do that but if it is useless maybe you could say sincerely thanks a million but would you mind sending me an alternative sample that I can actually put in my mouth.

I don't understand why he would attach it to a bolt? What for? Good luck with it Bex and keep plugging away until you finally get what you need.

Take care. I am off to a 40th B'day bash - the theme is Tropical Island nights. I look ridiculous but am determined to have a great time. I am not going to let this insidious metal ruin all my fun. Bye for now.
