There are times when I am running "specials" and will offer half hour sessions, but not on a regular basis. I prefer an hour or longer to fully enjoy your company!
I do, however, offer haf hour dates after we have become acquainted, but again, it just depends on my scheduling and mood. I hate being rushed, but understand time is not always of the essence, so as a courtesy to returning friends with limited schedules I offer less time, from time to time. Make sense? lol
