DNJ is a very experienced and wise DBer. Take this advice very seriously.
Any responses within 24 hours are likely to be highly emotive, steeped in trying to pressure/trap/punish them and completely the opposite of general DB principles.
I’ve read hundreds of accounts where newbies regret getting into a heated or emotional discussion and regret not thinking about things, coming to the board for advice, and then responding calmly and rationally.
I’m yet to read ONE post where someone attributes the loss of their marriage to not responding quickly enough.
