Yeah I can relate to the sensory overload thing. I need to be in peaceful and quiet places to recharge- I just don't have to be alone. I'd be fine with one or two other people in a quiet place. But I think it's actually more natural and healthy to be in environments which are not overstimulating; it's another example of the modern world disconnecting us from what is most harmonious. Some people seem to thrive on stimulation, but it would still be more healthy for them to learn to deal with less of it. Like we are have become addicted to sugar, caffeine, and other stimulants- sensory over-stimulation is another drug.
