Tell you what, it made my day to find that today's 9 am spin class was being taught by someone who is about 8 months pregnant. When I got there, she was talking to a class member, about 7-1/2 months pregnant.
Then, as she started the class, she announced that she'll be here for the next 4 Mondays, then gone for 3 weeks, then back again. Someone said, "You could take more, you know. They give you 7 weeks, don't they?" And she said, "I only need 3."
Then she pushed herself as hard as she was pushing us.
Like I said, it made my day.
