It's a long shot, but you (female, mid-thirties I'm guessing) and I (M38) crossed paths a few times at the Safeway in Terra Linda no more than 45 minutes ago. I was wearing a Giants cap with an orange brim, black Adidas track jacket, and a white N95 mask. We first ran into each other in the cooking aisle—I was trying to go for evaporated milk and there was a father/daughter there who were blocking us. We then queued up in the same checkout line. You have blue/green eyes, brown hair, were wearing black yoga pants, and had a bunch of 12-packs of soda on the bottom of your cart that you had to pick up for the cashier. We kept glancing at each other and I was tempted to say hi, but the opportunity didn't present itself.
Anyway, in the .0001% chance you see this, let me know if I should've said something to you :)
