I was about 18 months old and my parents (and I) went on a trip to a mountain park, and there was a terrifying lightning storm. Now, being parked in a little tiny dinky truck box RV on top of a mountain a kilometre high while lightning is flashing through the room every half second, while you can watch it trail down into the valleys is extremely scary, especially to a dumb idiot baby who doesn't know any better.
I remember staring out the window for what seemed like a good 5 minutes before I started to cry and then mom did that whole boob thing.
After that, my next memory is a bunch of spotty stuff from when I was about 4 years old to now.
