If I have to meet with a man for business reasons, it’s in a public place and I take a friend with me. No one can ever say boo.
I have done this. A lot of female business contacts I have to meet are around half my age. I don’t want them to feel “creeped out”.
I have an “open door” policy.
Which is to say I never meet with anyone behind a closed door unless it’s a group.
