How much warmer is their hug? How vulnerable it is?
That is my difference, how I look into the relationship.
A hug, the way they greet me and I greet them. The way I try to connect silently with no words.
The way I think of them is all about the way our bodies interact, not what we say, but how our “start/finish” behaviour is.
There are so many different hugs, so many ways of saying goodbye, and you can tell the difference.
You can spot a bad moment in their life just by looking at how they greet you when you come and go. How much they hug you strongly, how personal the kiss on the cheek is.
Some take distances, some do not.
