Hm... well, there's two options. One memory was when I was two, and we got our first dog. That happened a month before I turned three. Another memory is of me in my old garage sucking on my toes, which tasted kinda like mild salt.
When we got our first dog, I remember the dogs would untie my shoes, and I was trying to tell the man that the dogs were untying my shoes, but I felt trapped with such a small vocabulary.
