- Who are your fave clients?

They arrive on time, they're nice, respectful, good humored, clean, sane, have a life, they genuinely like you, they don't push your limits, they know  the rules, they understand the lines between fantasy and reality and don't blurr them, they bring you flowers on your birthday, they don't ask too much about your personal life, don't text silly stuff between appointments, they're appreciative, they tip and they leave on time.

Those are my fav.

(In my experience it's the married guys who make better clients and tend to "comply" with the things above, it's the lonely  or single ones  who tend to get clingy or have the time and the energy to drive u crazy  that are more difficult to deal with).
