I am an odd number. Take away a letter and I become even. What number am I?
Take away my first letter and I still sound the same. Take away my last letter I still sound the same. Even take away my letter in the middle I will still sound the same. I am a five-letter word. What am I?
Sometimes I annoy you, sometimes you can't live without me. But no matter how hard you try, you can't destroy me. What am I?
Without a bridle or a saddle across a thing I ride a-straddle. And those I ride by help of me though almost blind are made to see.
I am one small little piece of paper yet sometimes hold lots of value. I am all you need to get in to big events but will cost you. I am an important part of travel. And if lost you're not coming.
Give it food and it will live, give it water and it will die.
