Answer:
I am an odd number. Take away one letter and I become even. What number am I?
The more of me there is the less you see.
I can climb mountains, cross streams, handle hundreds of feet each day, yet I never move. What am I?
I am a protector. I sit on a bridge. One person can see right through me while others wonder what I hide.
I can fly but I have no wings. I can cry but I have no eyes. Wherever I go, darkness follows me. What am I?
If I say "everything I tell you is a lie", am I telling you the truth or a lie?
