Question: How is August 5th the day to take out the trash when July 5th was also?
Answer: The city may have fluctuating trash days. Or more likely, the July 5th schedule wasn't the regular pick up day due to the July 4th holiday.
Answer: To my knowledge, the purpose of hitting herself was two-fold. First of all, a facial injury would support the idea that she was abused or in some sort of bad situation. And secondly, to help mildly alter her appearance, so she could blend in more. (Especially considering people were looking for her).
