It's easy. I post a riddle and then next person gives an answer doesn't matter whether it's right or wrong. Then they make a new riddle and so on. Here's mine.
a man if found dead in the middle of a field with no cut,scratches or any other obvious cause, all they found was a rucksack next to his body, how did he die?
Suffocated himself?
Here's a new one. Different lights do make me strange, thus into different sizes I will change. What am I?
