'Missing' Thing

An old random string of thought worth including here:

What exactly is missing someone?
What does it mean?

Everywhere people say 'i miss you' 'av missed you'. Is missing of thought or of illusion?

Do i all the time think of that person that i claim to miss and that is how i knw i miss them?

Or do i simply notice their absence in all that i do?

Noticing their absence is indeed done in thought.

But is that noticing of absence natural or is it manipulated by your mind?

Do you notice absence out of the blue, like the physical body for example triggering this.. Or do you notice absence consciously? And do you control the noticing or does it just happen? Can you sit down and tell yourself..okay now I will start 'missing'? And will this be real or rather fake?

Wait...is missing all in the mind? Whether triggered by my physical surroundings or not..it seems to be all mental. And if it is all mental, is it affected by my moods or emotions and vice versa?

Do i 'miss' more when i am sad or it more when am happy? To answer this question..how the heck would i even measure amount of missing? 'I miss you loads' 'I miss you so much' . How do i know when its 'loads' or 'much'? By the length of time I have been doing the missing or by the object of my missing?

Can i say 'miss you loads/much' to everyone or just those am emotionally(or whatever other way) attached to or want to be attached to?

In that case, am i really missing them or just wanting them around?

Does my number of thoughts about someone actually measure my 'missing'?

And is there a timeline for this thing called 'missing'? Can I say 'missing you' to a person after one day in the same capacity as I would to a person after twenty years? Does 'missing' have a timeline or deadline?

Is it all about emotion and feeling? Or an occupation for an idle mind?

If it is all about emotion and feeling, then could it be a mere creation of our minds? A mere side-effect of emotion?

There are many emotions.

Can i actually miss someone i dnt like?

Like my high school matron?

Can I?

Is missing also determined by amount of time spent with the person or is emotional attachment still a bigger influence?

I dont at all miss the random guy i was in a lift with.

But for sure I would say I miss my long-term friends who have been overseas for a couple of years for their studies

Is missing or using the words 'missing you' also a feedback trigger? Like someone telling another ' I miss you' only so that he can be a judge of the other's emotional state and if 'I miss you' is the reply..then the feelings are 'mutual'

Actually, is 'missing' a tool or an end?

Be careful where, how, why, to whom and at what moment you doing this missing thing.
