When I was about 3 or 4, I didn't know what "yesterday" meant. She when I asked my dad, he said "Tuesday." So, naturally, I thought yesterday was another term for Tuesday.
Later, when my mom told me we were going to the zoo on Tuesday, I got in a heated arguement with her if we were going to go on Tuesday or yesterday.
