Actually, I noticed your son first.
I was pretending to eat a hamburger my preschooler served me from the play kitchen and watching my toddler grill plastic scoops of ice cream in the barbecue when your boy walked in.
He picked up a rubber stegosaurus and started to play, wearing a bright orange pajama top and a pair of blue pajama pants festooned with rockets.
Did I mention that the orange top was from a pair of Halloween pajamas, covered in pictures of the fake vampire teeth kids wear?
Or that both the pants and the top were long-sleeved, and it's currently 80-degree weather in August?
Or that the top was backwards?
Possibly you noticed me and a few of the other moms in the library staring, and I want you to know that we weren't judging you.
We were thanking you.
Thank you for not being afraid to go out in public when your child didn't look like he was doing a photo shoot for a Children's Place catalogue.
Thank you for letting us know we're not the only ones who don't always have it all together.
We're not the only ones who've arrived at their kids' dentist's office, out of breath and barely on time, only to find out the appointment is actually tomorrow.
Or gone on a day trip without double-checking the diaper bag, and had to improvise by scooping out a poopy diaper and lining it with paper towels from the restroom at the science museum.
Or taken our preschoolers to a sibling's parent-teacher conference wearing a T-shirt and shorts, snow boots, about 100 Mardi Gras necklaces, and a handkerchief tied across one shoulder like a sash.
Or mingled at a family-friendly business function after a child's diaper leaked all over our laps.
Thank you for reminding us that we all need to choose our battles, and that some days you just need to get out of the house even if it means getting some raised eyebrows because your kid only wants to wear off-season pajamas that are mismatched and backwards.
Thank you, because that was us yesterday, and it probably will be us tomorrow.
If I stared at your son this morning, it was only because he made me feel normal. He reminded me that being a mom is hard, and we're all doing a pretty good job at it, anyway.
