Go-No-Go

Supposedly going to a luncheon forum next week.
When get to know the organizing firm, there's a weak but distinguishable 'ding' in my head.
Quickly look at the key speakers. Bingo.
There's one whom I met quite some times and fought quite some battles before declining to join his organization that many months ago.
Would never know if better-off. Sure should stay away from this thinking trap.
Maybe, good to see an old "friend" again.
