All That He Wants

 Isaac suddenly said, "When I'm twenty-one, I will get everything I want."

I remarked, "Oh, you'll get everything you want?"

He replied, "Yes, not just cotton candy."

Ages

 Isaac is grieved that he is the youngest child. He is very conscious of everyone's ages, the year they're born in, and wishes he was the firstborn. One day he said, 'I wish I was born in 1999."

I asked him why.

"Then I will be two years older than Matthew."

Matthew is his eldest brother born in 2001. 

Another day I was driving Isaac to school when  he suddenly said, "One day it will be three thousand and one."

Puzzled, I asked him, "Three thousand and one what?"

He tried to explain and I finally understood what he was trying to say. "Oh, you mean the year 3001."

"Yes," he replied, "And Matthew will be one thousand."
