Had my first flat of my commuting career this morning. Naturally, my CIO starts blowing up my personal phone 30 minutes before I am even supposed to be at work freaking out for no reason, and when I tell him I am trying to fix a flat and that I would be in at my normal time, he starts insisting that he come give me a ride, to which I inform him that changing a flat on a bike is a 5 minute deal. I get the flat repaired... pass him driving the opposite way...
