“All he ever knew of her was who he saw every day. All I am is who I am every day. All anyone is to anyone is a series of days.”

Tired of running at sixty-six terahertz, tired of all those processing cycles, every second of every hour of every day.

One day, when you are looking, it’s not looking, no one is. You lie in your bed and realize that if you don’t get out of bed and into the world today, it is very likely no one will even notice.”

“I was headed for an entire life spent alone, pitying myself for not being more, ignoring all those people who actually ask me to be more, because they see it in me.”
