ok - i just read your other thread.
i would be FURIOUS!!!!

oh my gosh. i'm so proud of you for sending that email, i probably would have just quit with T right then and there.
what he said "if you don't do it, then i will" is like completely taking control of the situation away from you. and then expecting you only to call back to let him know you've done it. what a jerk

.
i hope he is able to clear the air with you today. i know he is your T, and you usually have a good relationship with him, but right now i am SO MAD and triggered on your behalf.
i have zero idea on why he thought his response would have been appropriate.
*deep breath*
to address your other concern (why they parked in front of your house) - over here at least, these is something quite common to do. something about privacy for the family, and also possible safety for the workers who go into that house. i think it was just a coincidence that it was your house (and maybe also that they dropped by to leave a note?), it could have been anyone's house on that street.
also, i'm glad those children felt comfortable enough to disclose that you stopped them. it sounds like they are cooperating and not being overwhelmed by what is happening.
i think you've done such a brave and important thing, sweetie. i cannot stress how proud i am of you, and how much in awe, and how grateful i am that there are people like you out there who are willing not to turn a blind eye to this sort of stuff.
