Answer:
I am milky white and scares people.
My first is in riddle but not in little. My second is in think but not in brink. My third is in thyme but not in time. My fourth is in mother but not in brother. My last is in time but no t in climb.
I can speak with my hard metal tongue. But I cannot breathe for I have no lung
With a halo of water and a tongue of wood, stone as skin long I stood. What am I?
I am used for light yet I am solid. Without me you would feel enclosed. I hate being touched especially with a lot of force. I like to be in buildings.
What is always coming but never arrives?
