the internet, on the phone. it's bad for you in the way that caffeine is bad for you -- it feels great. you feel sharp, focused and like you can do anything! yet, withdrawal from it makes you said, cut off and crabby.
it's nice to feel like you can walk away, but yet you always seem to come back.
and substitute you for i here.
