Man is the measure of all things
"The Pomfret's are tiny in the U.S.", is what I thought when I first saw a Pomfret fish in a U.S. shop (the Chinese stores have them). Turns out, they're regular sized Pomfrets and it's just me who'd grown. That's what I figured after asking around. I realized that I had last eaten this fish when I was pretty young (and small). So, my memory of their size was relative to my own size then.
Ever met people who spent their younger childhoods in a city where is snows and the piles go up to 3 or 4 feet, and and then they moved when they themselves were about 4 feet tall? Many of them, as 6 foot adults will say it used to snow and pile up about 6 foot high when they were kids! Damn this global warming!
I suppose, in this sense, man is the measure of all things.
