More annoying things in the middle of the night

I get home from work around 2 am the other night. Hit the button for the garage door. Door raises...stops after 2 feet. I repeat several times. Finally go in and peer at the darn door. Something is wrong...it just doesn't look right. Turns out a torsion spring has broken. Apparently a self repair is far too dangerous for any mere mortal so I'm hunting for a good door repairman.
