Yep, same here. Sounds like my life except I got into hiking and boats. Love time in the deep woods, you know those places where most folks don't go. Saw rare orange salamanders during a long hike while it rained off and on all day. Told the park ranger and he said "No one ever sees those anymore, where were you again?".
It's just a job. You just have to work with them you dont have to sign a mortgage or marry them. Just get through the day. Fix your shit and it'll run all night/week and they wont call. Train the users properly and your job can be a wonderful thing. They are just like the sheep and the puppies we all bitch about all the time. Realize the goldmine that this is and you will do well. They can be trained. If they ask for help and you dont help them they will yell. Yell at you, yell at your boss, yell at their boss. If you force them into the squeaky wheel role then you are not doing yourself a favor.
Try this instead, fix everything, train everyone, be there as fast as possible with an apology and a nice little witty joke. Be nice and they'll appreciate it. Tell em stuff like, "Wow there is no way I could possible do your job". A little honey goes a long way with a worried, stressed out user.
Anyway, nice post for an AC. Can't believe I just wronte a long reply to someone who will probably never get it. Damn AC posters. SlashDot.ARRRGH
