I hate:
...small little children that keep crying and making stupid noises, whithout any particular reason.
...when people ask me unproffesional questions about IT
...when somebody beside me is listening to the radio/tv in a language I cannot understand
...when the lights go off and when I look out the window I see the door of the transformer in the yard open
...when I take the phone and the person at the other end doesn't speak and/or hangs up
...when the person on the phone doesn't care to sey hello
...when my phone is not on it's traditional nail: although it's usually me who takes it off
...when I have to reinstall my modem
...people who talk anout god and religion
...people who read morals
...people who bring up anproven and unbalanced statements
...people who talk continuously
I guess that's enogh, though it's far not everything
