"you should never be alone with other women. Always have a bodyguard or something"

I mean, each to his own, but there are times when I would not want a bodyguard involved.

It's something someone I know that they suggested after observing so many people who have affairs, and it always stemmed from private settings where a married person and an unmarried (sometimes married, but less likely) person wound up having an affair usually emotional vulnerabilities or business was involved.
