I don't high five. Ever. I have given a few in the past, but of even that I am ashamed.
This can be the social equivalent of the dog who can't wag his tail, but I flatly refuse. Whenever someone asks me why I don't, I tell them to wait, and an example will reveal itself. Usually within an hour, some inebriated fratboy goes crazy over the slightest provocation, and demands multiple elevated hand slaps from everyone around.
My case is made.
I spend a lot of time in my head. It is like a time share in an area I love, with no neighbors, and all the other tenants blissfully absent.
This can cause problems closely akin to lost time. I will see a strange situation or interesting person, and will begin to unravel this intriguing mystery, and before I know it I am already at my destination.
My autopilot is strong, and takes instruction from my interior air traffic control exceptionally well.
I like a lot of time alone. Not Unibomber in scope, or intensity. Don't let the photos fool you. A few hours a day to collect myself and enjoy some silence.
Some have taken this as distance, but its nothing personal.
I think the best relationships often have the feature where both parties can share the same space, but have the ease of being alone, with the special comfort only the other can bring.
I have cycles where I am very outgoing and sociable, and other times when I would rather spend more time at home, or jogging, or rock climbing. I can't help it there are no rocks around here large enough to climb. If there were? They wouldn't know what hit them.
