I saw a lady do a 3-4 second happy dance after dropping off their kid at daycare (out of sight of kid). She suddenly stopped mid stride of her walk to happy dance, then leaped and skipped to her vehicle after the dance. I thought it was a little strange at first, but then I chuckled.
No idea who this stranger is, but I couldn't help catch a little bit of her infectious excitement and happiness. Thanks stranger! I kinda needed that today.
