ONE

Toilet training looks something like this. (Back story: DS has a sticker chart where he earns 1 sticker per toilet attempt. At 50, he can earn a coveted toy.)

DS retires to the washroom.

Me: Would you like to try using your toilet? You'll earn another sticker toward your backhoe if you do.

DS: No thank you Mama. That's not an enticement.

TWO

Me: DS, would you like to play "Go Fish" with me?

DS: No thanks Mama, it's not to my taste.

What is to give light must endure burning.
