that can take a great day and turn it into "I want to hurt someone" moment...
For me it's printers... I expect the printer to work when I send things from my computer, through the wireless underworld... and my results is happily waiting for me in the tray... it just drives me to the point of insanity when it doesn't work that way...
Oh - and when I have a hybrid project that I would like to get done for New Release and hubby decides to unhook everything to clean... doesn't tell me and until I'm standing in the front of the printer wondering where the hockey sticks is my printables????
What is your sane item that can become a hot trigger in under 60 sec flat?
