Hi there
That`s good choosing riddles ,dear
You`re a simple man but ,in my opinion, they are not simple.
They want a lot of time thinking to their soluions
However, I puzzled over them fast
I tried my best quickly but got only few answers and they might be wrong, amigo
I am not smart enough to solve them but I will give you the answers which they might be right in my opinion
1-what goes through the door without pinching itself maybe the ghost
2-goes away and never returns maybe the time
3-What sits on the stove without burning itself maybe the water
4-The second eats as much as is given to him, yet is always hungry maybe the fire
this is my suggestions and I am looking forward to their correct answers.
