Not necessarily pool as in the sport, more from the trolls and such. It's really up to David to explain it, I'm just relaying the outlines here without revealing his personal life. We have been good friends for almost 20 years now and I have some boundaries as to what all I share about him. I'm sure if you send a PM on FB and he is up to it, he will respond, but I can't promise anything on his behalf.
If and when David chooses to respond, I can certainly repost it with his permission but I won't pester him as I wouldn't any of you either. Well except for 14.1 knowledge of course
