Miners work quickly to have me but they cant see, touch or smell me. My value is greater than you think but if you lose, me I'm gone forever.
What am I?
I am large on Saturday and Sunday. I get small from Tuesday to Thursday. You can't find me on Monday and Friday.
Who am I ?
I stare at you, you stare at me.I have three eyes, yet can't see.Every time I blink, I give you commands.You do as you are told, with your feet and hands.What am I?
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. What am I ??
