My family was headed to an aunt and uncle's home for a party. Whilst driving across a bridge at ~80 km/h the spare tire mounted on the back of a motorhome fell off and bounced along the road. My dad was driving behind this motorhome and could not avoid the tire. Had the timing been off and dad hit it while it was mid-air it is quite possible it would have smashed through the windshield, killed or debilitated my parents, and we may have crashed, thus killing me. Fortunately we hit when the tire was making contact with the road so the brunt of the damage was borne by the car.
No I have never been fired from a job. If I was I imagine I would not have been upset about it. If I was doing so poorly they fired me I probably wouldn't have wanted to be there anyway.
