Working Mommy is exhausted

My friend Valentine went back to work after taking the Christmas to New Year's week off. She has one child, a boy around my Boy's age. They are best friends. She is a research scientist for one of the big biotech firms around here and puts in a boatload of hours each day. Her job is really intense and really interesting (even though I don't understand half of it).
During the week off, she let her nanny take the time off to visit the nanny's family in San Diego. Valentine was in charge. She was cooking, cleaning (the cleaning lady was also off during that week) and taking care of her son. On the first day back at work, she emailed me saying that it was too hard to do all those things and she was grateful that her housekeeper and nanny were back at work (the cleaning lady comes by once a week). Her actual sentence was "thank God the nanny is back to do this!"
I had a good laugh and told Husband about it. He asked, "Does she realise that this is what you do every day?" We both know she didn't even think about the fact that my life is about cleaning, cooking, watching Boy and trying to keep Husband happy. Valentine is the woman who constantly asks me if I'm sure I don't want to go back to work. Of course, every time I've been at a party with her friends, they all are overachievers with South American nannies/housekeepers who can't understand why I'd give up all that Gloria Steinem and company fought for.
On another note, Nosy Nancies can be male.
Today, Boy and I were out running errands that we couldn't do during this weekend's nasty storming. As we went out to buy Boy new jeans, he decided to dump the contents of his sippy cup all over his sweatpants. It appeared that he had peed through from the front to the back of his crotch. After telling the cashier that no, my son didn't get ignored in his request for potty time but that he had spilled his sippy cup all over his crotch (and getting the 'likely story' look from her), Boy and I went out to our car. As I hoisted him out of the cart into the car, a man sitting in the car in front of us spied Boy's wet front and rolled down his window as I returned from putting the cart in the cart corral.
"Your son peed his pants."
"He poured the contents of his sippy cup onto his sweats."
"No, he definitely peed his pants."
"No, he poured water onto his pants. He thinks it's funny."
"It looks like he peed his pants. You should change his pants."
"I'll get right on that."
The man looked less than pleased at my dry final comment. I got into my car, started it up and reversed out of the spot. Boy was waving his almost empty sippy cup around like a little mad man was we drove out of the parking lot. I wished that the windows on our car were less tinted so Nosy Neil would've seen what boy was doing.
