I asked the lady behind the supermarket deli for 250 grams of shaved ham.
She picked up a handful of meat, dropped some of it, picked up a little more. The scales showed 280 grams.
"Sorry, I was guessing," she said, apologising for not being some ham-measuring cyborg, I guess.
"It's okay," I told her. "I was guessing how much I'd even need."
I think that's what everyone is doing in life. Doing their best, guessing. That's what I guess.
