How does it work with "missing" somebody?

Who are then ones that we miss them and

why do we miss them?

Should we tell them when we miss them?

I don't know the answers to these questions exactly but I think:

There is a characteristic in any relationship and there is something flowing between two individuals when they have any kind of relationship.

Whenever you need what you get from a special human link, then you miss the one who you find it with him or her.

And I think "YES", it is very important that you let others know if they are important for you or you miss them. And more important is that I think it does not matter how they interpret it but it matters how you interpret it honestly with yourself.

If you consider it complicated it becomes complicated but if you take it easy it goes easy.

Love and Peace to You!
