i was 5. my mom was running erronds and drug me along, so when we walked into a bank, the teller asked me my age, i said 5. that's the only reason i know it was 5.
i thought i remembered being 4 and seeing some thing called "sun city" or something in Mesa Verde, and walking around all over it (was like 4 foot high walls, brick, allowed to walk on). but when we went back there, it looked nothing like i remembered it, so i think i formulated that memory.
just like i'm sure i formulated the memory of sitting on someone's shoulders flying through a hallway in our familie's oldest house (the one we owned long before the house in LA. and LONG LONG before this house). but i'd have to be 2 for that memory to be correct.....
