I laugh

When something is very deadly serious.
When I was 21 I fell onto an old goldmine, there was only a thin layer of dirt covering this 100 year old goldmine, I was laughing so hard I could not get onto my feet. The earth below me fell away and the only reason I did not fall to my death was because of the safety rope around my waist.
I thank Darren every day for making me put the safety rope on.
