I have the feeling, my old boss will knock at my door one day too. Unless he'd chicken out, since 1. I am pretty sure I'd recognize him over the phone, 2. I am sure, he will recognize me too.
I haven't got his mobile number anymore to block him, and I suppose he wouldn't use anyway the same mobile to call an escort. I'd wish we'd go ahead though, since I've always fancied him, but also it will put me in better situation, than being recognized over the phone only.
Don't worry, he won't tell anyone the true story
