A heartfelt apology

While I mentioned in Not Stuck , “thanks to those concerned”, perhaps I did not illustrate clearly that I was suitability moved by the genuine concern of close friends regarding my plight, and I did really appreciate the comments and initial feedback.

I’ve talked with close friends such as Jay , Frank , Marc and tonight both Giuseppe and Sheeri and while I’ve been told it’s a good one, and we laughed and smiled I do value the genuine friends I have in the MySQL Community.

My apologies for any personal pain cause during April 1st. I hoped that I’d replied via email to each commenter promptly to minimize any additional delay.

And sorry Marten, for the lost productivity as I’ve heard about, I guess I owe you one.
