Often, but there isn't much that can be done about it, Even worse is when it occurs and I'm surrounded by the really ugly and un-feeling people that are walking around like they're already dead. Can't explain that one, and that description isn't based on age or physical appearanc, or the amount of noise a person is making at a given time; it's as if sometimes I can look at a person and see a big diseased, empty void instead of a healthy person. Then I pull back even more and miss physical contact the most.
