Frequency

I have a theory that everyone has their own frequency. That means, someone's frequency is unique.

i don't know if i missused this term, but what do i mean by frequency is like a character of  a voice.

and if you're pay attention to someone's frequency, you can always hear it, you can always distinguish it from others. even if its too loud, even if its too crowded, or maybe even if its far away. and maybe even if you're busy with something.

well i just realized it today, it's just my opinion though. but it's interesting :)
