If anything, I think this text exchange proves my point.
He was just asking. You’re the one that jumped to a conclusion.
Try this instead…
Client: “Are you single?"
You: "No"
If they keep prying…."I’m sorry, I’m not comfortable talking about my personal life".
But at least give them the benefit of the doubt in the beginning.
Otherwise, I think you might come off looking defensive and not very personable.
(Hopefully this comes across right. I’m honestly trying to help. Not be a dick.)
