What are some signs that a therapist may have poor boundaries with their clients?

Off the top of my ancient head:

Obsessing about clients outside of work hours.

Frequent phoning or texting of clients to “check up on them and make sure they’re OK.”

What are some ways to improve speed in sprinting, running uphill, and long/middle distance running?

Serious disappointment when the client cancels a session.

Sense of competition with persons who are important in the client’s life.

Session-expressed curiosities about client details not relevant to the therapy.

We white women don't like white men. Do you have any issue with that?

Routinely going over the time limit with certain patients, compromising the time for the next client.

These items can happen fleetingly, briefly, in any therapy, but if they’re frequent, it’s definitely time for the therapist to get some good, solid supervision/consultation.

General Introduction to Boundaries from Panahi Counseling:

I'm a 27 year old male currently but I am going through going through gender dysphoria. Why do some transgender people (specifically transgender women since I see that the most) call themselves trannies or shemales? Aren't those offensive words?

Disclosing feelings, fantasies, and experiences to the client in ways not related to the work the client is engaged in.

Struggling with fantasies of deeper connections with clients, whether sexual or parental or other intense or intimate relationships beyond psychotherapy.

Failing to mention the client in supervision/consultation, out of fear the supervisor/consultant will advise return to ordinary healthy boundaries.

Eager anticipation (or anxious anticipation) of the next session in ways that distract.
