I think Chesterfield might admit to exceptions. If not, he should have. The interesting thing here is that, in advising his son, he casts a wide and secret net over the subject. My preference currently is to be above board in speaking with and about not only the ladies, but anyone whom I encounter.
Well, I also think being above board is the way to go. I try to be humble and gentle with it, though. I’ve regretted my words often enough.
