Things I remember from a very young age:
My sister climbing the bookshelf to get the green stamps out of the shoe box they were kept in.
My sister sticking green stamps all over me.
Saying, "Mommy! Mail me!"
Mom losing it, then laughing like crazy.

I recently brought that one up to my Mom again. We decided I was about 2 or 3 at the time. She had forgotten that we went to New Jersey twice. She kept insisting that I was only about 3 months old, and I *know* I said "mail me"
