I tended to, when told not to do something, do the thing anyway as a kid. I learned, over time, to curb that urge, but I have a small list of things I did before that happened...

• Ascend a power pole, despite being told not to. Because, you know, it was dangerous to do that. But little me just heard: DO IT! And then did it.
• On a trip to the beach on a windy cold late Fall weekend day, was told not to touch the globs of black oily tar, tossed onto the beach by the waves, since there was nowhere to wash my hands—other than in the icy cold ocean. I did it anyway, so the goob was rubbed off, as good as it could, in the sand, and then washed at the restroom in the parking lot.
• Put both my palms on the hot stove top.
• Stuck a vitamin tablet up my nose at daycare. How could I not, when they put a tablet on our plates, to take with our lunches? Gold, for a little of 4-years-old kid like me.
