I agree but, as I said earlier, it's starts with either the conversation (if we're sitting close), or the eye contact.
I've seen women make eye contact with me and then smile. I might or might not approach them, depending on their ring finger and their looks (I'm old fashioned; I do honor the ring).
Others will look and then look away, so I'd guess they're not interested.
Others have come right up to me and started a conversation.
And others might talk for a few minutes but then leave or say something that tells me that they're not interested/available.
It's sad but there is a certain game that has to be played...and I hate it! People should be up front and just say if they're interested or not. It's not pleasant to reject or be rejected, but it sure beats the alternative (avoiding the phone calls).
"Afield", is that in southern Maryland?
