My first T years ago showed up at my house unannounced. I was shocked to say the least! I was also mortified by my messy house and would not let her in. I opened the door a crack to talk to her. If she had called first, i might have had some time to tidy up, and get dressed, lol.
A few years later when my car broke down, she did make house calls. I had several sessions with her in my living room. My 2 year old gave her a tour of the house!
