When is the last time you cried and why?

i am a strong-minded boy and i seldom cry.but one day i cryied,maybe it is my last time to cry.do you know what happend.
that is you don't take my answe

the last time I cried is because my brother tried to commit suicide in my room where I hide all my dirty underwear. I was very upset because if he killed himself in there, the police department will see all my underwear with yellow stains and possibly laugh at me. So I cried.
