Answer:
If two's company and three's a crowd what are four and five?
I am easy to see but no one likes looking at me. Without me there would be no you. I can make you complain or make you happy. But you almost always take me for-granted.
You shoot me but I don't die. You hang me but I don't die. What am I?
I am just two and two. I am hot. I am cold. I am the parent of numbers that cannot be told. I am a gift beyond measure a matter of course. I am given with pleasure when taken by force.
I only exist when you are here. Where you never were I can never be.
How can you tell when a mummy has a cold?
