There is no contradiction at all.
As stated previously I did not request that Randy ride the board ( which was claimed to be the case by a poster on this thread) I heard from the person who was looking after the board that Randy had decided to ride it. I had no contact with Randy until after he rode it.
So, Randy rode the board at his own request not mine, and I did not say that he rode the board without my knowledge, as you have claimed. What you have done is change what I have said in an attempt to create a 'contradiction' where none exists. That is a classic informal fallacy in argument known as the 'straw man'.
Which part of that do you fail to understand?
