He was so use to the same old crap being ignored and kept out. Once he went into the world people found him interesting and talked to him. It was all new and different. Stuck in a routine only working and sleep the world seemed so young and fresh while he was was older feeling dull.
Missing his youth because the new generations filled in those empty slots. While his peers had kids got married or just working a mind numbing job that occupied their time.
Feeling hidden from the world trying to stay in control even though things are out of control for the most of the time. Broken from the past feeling healed like a whole in the present moment. The transition was very complicated always starting over with relationships or friendships learning to not get attached since people are usually just passing through.
