Check bags are fun. I just make sure there won't be anything illegal in my check bag which is forbidden at a cabin of a plane. Just leaving things like scissors and such out of my carry-on things in order to avoid troubles with some certain airline, y'know.
The only time I can really relax is up a tree or somewhere outside. I love being outside.
God, our genes, our environment, or some stupid programmer keying in code at an ancient terminal - there's no way free will can ever exist if we as individuals are the result of some external cause.
