On calling your friend the computer guy for help. I will definitely go out of my way to help anyone that is in my path with computer problems – I’ve diagnosed dead drives for parking lot attendants that bring their home computers in after seeing my company car a few times and been late to clients doing it. My dad is generally very good about beer and a great meal in exchange for computer tweaking. I’ve otherwise become a hardline “drop it off at my office or house, I’ll call you when it’s ready, don’t expect that to be very soon” realist with my time. I definitely don’t build whiteboxes for people any more.
