It is interesting how we inhibit our actions in anticipation of another's reaction and are often wrong in our thinking.
We too often observe the behavior of others and really don't see them. Especially if those behaviors are what they think are expected of them because of past experiences. Just because a person is a certain way doesn't mean they're comfortable or like being that way.
Humans are complicated creatures which is why I prefer my dogs. They treat me the same, show unconditional love and it might sound strange but they have a better detection system for my emotions than my closest friends do because my dogs don't use a people filter. It's a far simpler filter.
