People and their belongings can be said to be waves which oscillate at a given frequency.
Friends are the people with which you harmonize well, or interestingly enough for it to work.
Hobbies are activities which harmonize with you well, or such that you are inspired to seek it out.
Some others are artifacts that your mind has embraced in such a way that you are it as it is you.

There is no such thing as a unison in this phenomenon.
No two waves are identical
but at the same time
no one is isolated.

All sing together to create the plethoric mono-chord of things we call 'Reality'.
Dissonance is there
but it is absolutely relative
as it is also relatively absolute.
