people's noise and generally their attitudes
You summed up right there.
I've realized that people add tons of useless noise after spending so much time traveling alone. I'm no longer used to receiving such a load of information. Sometimes I feel dizzy among friends--mostly old friends who do not follow the same interests as myself anymore--, so I avoid big meetings. Solidute is addictive; we get used to the silence.
I believe that many will never experience true solitude but am fortunate to have the chance to find it myself as I often travel to remote and unpopulated areas...It helps keep me sane. Mostly sane.. 😀
