I have one of the least addictive personalities of anyone I know and yet, lately, I've been glued to my computer like a teenager. My eyes hurt and I emerge into the fresh air feeling hungover and vaguely disappointed. This makes me sad for teenagers and annoyed at myself. Today I purposely stayed out of the house all afternoon, walking through a neighborhood I rarely get to, trying just to look at things in all their amazing three-dimensional glory, the way I used to before the computer made me slow and stupid.
