I would make certain boundaries were straightforward and easy to understand:

I would allow email if it was a short, straightforward question, giving information for the next session, or requesting an appointment change. I would let the client know ahead of time that I would let them know if they were emailing inappropriately.
Physical touch would be okay if I thought it was beneficial or therapeutic to do so.
I would accept small, meaningful gifts (something hand/homemade, cards, etc).
I would loan someone a book or video if I believed they would return it.
I would have a sliding scale and expect prompt payment (but would probably make exceptions if someone was in a real bind).
I would only go over the allotted time if the client was distressed, but would try to wrap up the session a couple of minutes prior to ending (any questions, summarize, give homework).
I would use a lot of interviewing in the beginning trying to learn the person and find out what goals the client has before deciding on a modality of treatment.
I would encourage the use of whatever aids helps the client in therapy; stuffed animals, blankets, writing, drawing, reading, music, etc.
I would ensure the client is comfortable with the seating arrangement and allow them to sit wherever they wish and decide where I sit based on where they want me to be.

I believe being a therapist is a rather difficult job that requires a great deal of flexibility, empathy, and acceptance of all people. I still consider going back to school to do it myself on occasion once my own issues are worked out.
