The most stupid thing I have ever done with my friends is probably eating ice cream in winter.
Something that many college students will try is eating ice cream in winter and feeling the biting cold feeling in your mouth in the cold wind.
At that time, just after the exam, I couldn't help but try the cold winter ice cream with my friends. You know, although the winter in the south is not as cold as the north, the humidity is very cooling. I stupidly sat on the grass with a few friends to eat ice cream, and took a bite of the ice cream.
I got lumps all over my body once, and the sad thing is that several people got sick the next day after doing this stupid thing.
