Susan's daughter ended the year under the effect of her first monthly menstrual cycle. Poor thing. She's got another 40 years of discomfort and inconvenience ahead of her, but Susan did her best not to let on.
The daughter had previously been prepared with both information and supplies for the wonderful thing that happens once a month, they've just been waiting. Now the wait is over. Happy New Year, kid.
Susan presented the Monthly Mess as a club that the daughter was now a member of and welcomed her with some chewable Tylenol.
