I am often sold by children entrepreneurs in summer time
I have a little house in which I live all alone. My house has no doors or windows and if I want to go out I must break through the wall.
I have keys but no locks. I have space but no room. You can enter but canβt go outside. What am I?
I touch the Earth, I touch the sky, but if I touch you, youβll likely die. What am I?
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
