Hi Michael,

Sorry for getting back to this so late: I have been caught on a spiral
of corporate commitments really difficult to get rid of...

We can discuss about those of my statements you don't agree with and those
of your statement I don't agree with in front of a couple of beers along
next meeting.

I think your proposal on an appendix makes sense. Let's go for it and make
things happen.

Be goode,
