when someone tells you "actually this email is FYI only... you didn't have to reply.." It also means "wth why send me a new email and add one more email to my inbox"
e.g. 因为价钱比较便宜而买了 1 carton,但是也需要找storage area 储存。可是 - i am just renting for the price of a room. That's how much I am paying for, and I have a limit at the space that "belongs to myself".
