how do you know something that very abstract existed or not?

ok first let define “abstract“;

abstract is something you cannot see, but feel

cannot be heard, but have to listen to

cannot be taste, but sense

cannot be touch, but have to hold deary…

the most abstract that i can think now are, love and ghost.

how can you define “love“?

and how can you define “ghost“?


you meet your true love or have you ever see ghost?


it’s all depending on what you define “love” and “ghost“.

you never define both?

then you never know even it appear before you; and so sad for you.

you missed something pretty excite in your life.
