..but email is fine. Sometimes the lack of an ad or post doesn't mean much.

Is her info still on TER? If so, I think it's fine to make contact.

Not sure if I am typical, but I was posting ads fairly sporadically over the past few months. When I would run into scheduling problems with potential clients, I'd tell to write me in the future whether or not they saw I had an active ad.  

I keep my "work" phone and email separate from everything else, so it's not like I'm going to have a family member pick up the phone by mistake. But I do understand that not all providers can afford to keep things separate (even though they really should if at all possible)

You don't need a letter of introduction or a flower.

If she's unavailable she probably won't even answer an unfamiliar phone number.  Just call her and mention her ad.  Be unapologetic but cordial and get right to asking if she's available.  Listen closely to her tone of voice for insight to her personality.

Thanks again people.  No recent option to email. A phone number search brings up an email that the provider was posting a few years ago so not sure if they still use it .  I have called but gotten a vmail option. I didn't leave a message but after the call I texted asking if it was her. Maybe not the right step but I felt a little awkward with no recent ads. Last one was in October.  I did that a few days before I posted this question.

If she's a traveling girl. I think you should avoid doing that. I have had several people (specially during my last trip) who "text or call" the day after I leave town. I mean... What's the point. U know what I think. They're too afraid to make that phone call when it actually matters. So when the girl leaves town you suddenly grow balls to reach out because the risk of actually going thru with it is gone.  

I'm not saying Ure like that, but... I don't know you so. Who knows. It happens way too often for me to care for people who do that sort of thing. if you really wanna see a certain girl. Then make it happen. If you like to fantasize about meeting her and texting her once she stops advertising or leaves town. That sounds more like a time waster's MO. Much like the people who call to tell us "they can't see us" or "if we can't stay another day" as if they'll pony up the money for the short notice flight change upcharge.  

Try to put yourself in the girl's shoes. I prolly sound nasty, but someone needs to tell you how things really are from our side. I'm trying to give you some perspective. Life is too short, take the chances that life gives you. One day the girl u wanna meet may just be gone for good. And you will have missed the chance to meet a great lady.

Why don't you ask her when she's going to be available, and pre-book?  

I realize that short-notice bookings are the way that many clients have to operate, but I very much appreciate it when I have clients who can make an advance appointment -- indeed, sometimes months in advance -- and who I can rely on to keep those appointments. Or provide me the courtesy of giving me a deposit or paying a cancellation fee.
