I can make a much shorter sad story NGL. Here's some

Sale: Baby shoes, never worn. (Sad because baby die)

Sale: shoes, never worn. (It's sad because the person who bought it doesn't understand fashion trends and bought them too late)

Sale: shoes, worn (sad because the shoes are going to be smelly)

Sale: baby (sad because selling baby)

Baby (sad because you didn't expect it but now you have to care for baby).
