This is what I emailed the section 8 lady:

My move went very smoothly. I have not yet gotten any mail at my new place, though I did change my address with the post office. I would like to make sure I'm not missing the letter from you that says what my portion of the rent is, now. If you have mailed it, or are not yet finished with the paperwork, I understand. (It may still be in the mail, as it is slow lately.)

Thank you, and I hope you are doing well-
