There are certain things commitment-phobes shy away -- neigh, bolt -- from: marriage, carpooling, children, buying a house, tattoos, wallpaper... Any one of these things would certainly send shivers up the spine of any free-wheeling spirit.

"Where will I be in 30 years?" is a thought that churns my stomach in the middle of the night.
