Answer:
What always ends everything?
I am a portal to another world which you cannot enter. Only you can see me but I can't see you.
You can drop me from the tallest building and I’ll be fine, but if you drop me in water I die. What am I?
I have numbers on my face but can't find 13 any place. What am I?
I can bring tears to your eyes; resurrect the dead, make you smile, and reverse time. I form in an instant, but I last a life time. What am I?
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
