Do you know this shorthand? FYI?
It means “For Your Information.”

It’s a great way to save time and space in text mail and email.
We even can use it in actual speech!
E.g. “John, I’ll see you at 6pm for dinner, and FYI, it’s your turn to pick up the tab!”  (Pay the bill).

I am currently in Japan right now, enjoying my time in Tokyo, Yokohama, and soon Shizuoka and Kyoto.
I’ll post again soon.

Thanks for reading!
