You have me today,
Tomorrow you'll have more.
As your time passes,
I'm not easy to store.
I don't take up space,
But I'm only in one place.
I am what you saw,
But not what you see.
What am I?
Sometimes I am loved, usually by the young. Other times I am dreaded, mostly by the old ones. I am hard to remember, also hard to forget. And yet if you do, You'll make someone upset. I occur every day everyone has to face me. Even if you don't want it to happen; embrace me. What am I?
