The absolute fucking rancid vibes everybody emitted when I took my kids out alone in public. I even had the cops called on me once, when one of them was throwing a tantrum at the grocery store. I am so grateful that I was paranoid about that exact scenario happening, and carried copies of the kids' birth certificates at all times. No officer, I'm not a stabber. Just a very tired dad. Kindly stop detaining me, thanks.
It's well over a decade since any of them have been that small, but the experience is still haunting.
edit: I just realized I still have the laminated birth certificate copies in my bag. I should probably get rid of them. Carrying around another grown-ass-man's birth certificate is weird for entirely different reasons.
