Earliest Memories

¿Por qué no recordamos los primeros días de nuestras vidas? I am learning Spanish on Duolingo and this phrase keeps returning to my lessons: Why don’t we remember the first days of our lives? My earliest memory is at my brother’s first birthday party–I was one. It is a memory of a day with my grandmother that I cherish, and my online Spanish lessons keep reminding me of it. -Michael Tino (CLF)
