Pornless Porn???

So for months, actually almost after I opened, this nice sounding black man called and was asking me questions, like, "I am interested in knitting and want to find a store that sells nice yarns and things"
Me- Well you have found the place and I am more than willing to show you...
He- I am in a local Reggae band and in between, I thought I could do this stuff
Me- That is a great idea
He-Can you tell me where you are located
Me-Well where are you coming from
He-Germantown
Me-Oh that will take a while and I close soon..so I give directions
He-I come pretty quick
Me-silence...more silence and then say well I close soon

Me alone in the shop, no vicious dog, is nervous now. Will he show up? was it just a prank? Am I going to be alone when this guy walks in knife in hand, telling me to do bad stuff, stealing my yarn while he sings Bob Marley tunes??? Poking me with knitting needles...oh man what should I do??? Ok, I have hornet spray strategically located all over the shop, yeah I know it's inconspicuous and sprays 20 feet and you will be blind till you go to the ER. I get one can closer to me. I am loaded and ready and I get to thinking.....I haven't had sex in umpteen years, if that is what he is after I may kill him??? He may say, I'm going to tie you up and I'm going to say "Oh baby bring it on" It's been a long time...put the knife away I am ready and willing ....are you? He may end up calling the police..Help me she is killing me."
Ok so my mind went on a tangent there...and please don't miss understand me there is nothing funny about rape or abuse, but if you know me, he should be afraid, very afraid.
Instead I call Chris the jeweler, and he sits with me till I close. He never showed, but I continue to get the calls periodically and sometimes he doesn't block his phone number, so I have it.
After about 20 calls, I finally recognize his voice and hang up or say something snide, he called yesterday and I told him one more call and I am reporting him to the police. Now in reality what can I say to the cops, "this guy calls me and asks for directions? " I have hornet spray...
I do hope if a black man ever calls and asks about knitting stuff and is legitimate, I don't start screaming obscene things in the phone.....that is not good for public relations???
