A while ago, I decided to lose weight after some serious reflection and bought an extremely expensive smart body fat scale. The scale is very advanced; it can connect to your phone, and every morning it sends you an "inspirational voice" based on your weight change.

I stuck with it for three days, and every morning I heard: "Keep going! You weighed 0.1kg less than yesterday. You're the best!"
On the fourth day, I was so hungry I secretly got up in the middle of the night and ate half a roast goose, plus a bowl of snail noodles.
The next morning, I stood on the scale with a heavy and guilty heart.
As a result, the body fat scale was silent for a full five seconds, then a pop-up notification appeared on my phone with a message:
"Please do not bring pets onto the scale."
Standing on the scale at that moment, looking at my reflection in the mirror—my face looking rounder due to water retention—I felt that this scale not only measured my weight but also directly measured my personality.
At that moment, the cool air in the room wasn't from the air conditioner; it was from that scale.
