I once spoke with a prospect.
We were a perfect match: i.e. we had a great connection, both enjoyed our conversation, and could see how we were going to work together.
She promised to get back to me in a week or two for us to get started.
And so I waited for 1,2,3 weeks; silence.
Then 1,2,3 months; more silence.
At about the 4th month, she finally got back in touch with me.
