The truth of the matter is perhaps she has some trouble in that area, sometimes I visit a certain area and get a lot of troublesome phone calls eventually I do not answer the phone if this is the case. I do not know the lady in question at all. therefore I am not coming up for a friend or anything like that just stating an opinion.
Sometimes if you have contacted someone by pm perhaps the way to do it is send a friendly text announcing you are member xxx and is she free to take a call, this way she will automatically know you are not ringing to cause her grief or harass her in anyway.
Its very hard sometimes in certain towns when your phone rings constantly and its malicious calls with intent to either place your location or to just keep your phone line busy, this then automatically causes you to become suspicious of every caller who calls and possibly what you percieve as a non-invasive question or polite question could cause the lady to think you are indeed up to no good.
Most ladies do not really like being asked the question are you working so possibly that could have been it. I am not sure at all but just trying to explain it perhaps from the escorts point of view. Hope that helped xxx
