Ninety-nine percent of the time Japanese people are very indirect when it comes to communication. It can be very hard to get a straight answer out of people. Instead you are more likely to get a bunch of hemming, hawwing, chottos, and teeth sucking. This indirect, borderline passive aggressive form of communication is something I've grown to hate over the years (especially since I feel its a major obstacle to forming real deal relationships), but I've slowly started accepting it as a fact of life.
However, there is that 1% of the time where all pretenses are thrown out the window and saying something directly is A-OK. It's when your ass has gained weight. Put on half a pound and someone will be there to let you know it in a heartbeat. It's not like in America where fat is a dirty word and has to be heavily coded. Nobody's like, "Hey there! Lookin a little husky today, kiddo!" or, "My, what big bones you have!". It's more like, "Daaaaamn, fatty! What's your fatass been eatin' lately? Lard on a stick covered in bacon fat?!" The kid gloves come off and the punches do not get pulled in this situation. I put on about 2kg over the holidays (General Tso's and mountains of fried rice will do that to you), and my co-worker tells me my cheeks got fatter. Wonder which ones she was referring to. Whilst out with a friend of mine one fine afernoon, an old lady comes up to her and straight up asks if she's preggers. Even my dumbass knows you do not ask anyone if they're preggers unless you see the baby's head dangling out their crotch, and even then it's best to wait til' the whole thing is out just to be sure. It is not a game out here, son!
Haters gon' hate.
