I won't close it, it's up to you, but you may want to mention that he did not know you were doing this, and it's a surprise for him, if that is the case. Looks better that way. Otherwise some may assume he's asked you to do it.
I read you. Thanks.
To whoever is reading this: please don't let my honest mistake make you think
any less of Mr. Lewis' ability. Again, I was doing this as an unsolicited favor,
and never ever did he ask me to do anything of this sort for him.
If any of you have a "problem" with me, take it up via PM.
