Sometimes I like to do things the hard way.
For example, sometimes** I enter things (like into spreadsheets in excel, printing a bunch of envelopes, etc) into the computer by hand.
Maybe I just don't trust the computer to do it right (or my ability to tell the computer how to do it right), but I think its more to validate myself, to feel like I can accomplish something without the need to use some fancy mechanical technological whing-dingy dealie-bob (say that 10 times fast). I just like to do stuff on my own.
**By sometimes I mean if I can get away with doing it while at work, and always when I'm at home.
