Hahaha, II love that you’re kinda faking them out even if you’re right or not lol. I used to work as a cashier, and I would always guess the weight of the vegetables/fruits before putting them on the scale/scanner thing because i love estimating that stuff too. I did it out loud once and got it almost exact and a couple customers jeard and wete impressed. So I tried a few times and the customers in line and I made a game of it and cheered or "awww"ed when I got it wrong. So fun.

I also like trying to guess the amount of something i need for recipes. Like, a recipe calls for a cup of onions, I look at the whole onions in store and based on size I imagine what it would look like diced in a measuring cup, I usually get close and its so satisfying
