I was three and visiting Korea. My parents and I went to visit Jeju Island for the weekend and we got to go on a boat ride. I remember the incident because it was a very rough ride and practically everyone on the boat got seasick. I specifically remember looking out the window and staring at the wild waves. I also remember other parts of my trip to the Jeju Island, such as visiting a museum and riding on a horse with my father, but the boat ride was my most memorable memory. My identity is same now as back then (probably.... I WAS only three...).
Wow you remember something from when you were three?! That's amazing :D I guess tough experience does stay with you for long time. I still remember the day I fell and some how getting my chin scraped on asphalt (or cement I guess) road.. And perhaps the other memories associated to that particular memory stays with you as well, which explains how you remember other parts of the trip. Anyways, other than the boat ride, it sounds like you had great trip:)
