An exchange my old coworker had with his son:

Timmy: "I don't like Mommy. She does bad things."
Daddy: "Well Timmy, that's why Mommy needs Jesus. We all do bad things at times. That's why Jesus had to die."
Timmy: "Mommy's sin is unforgivable. She disobeyed me and ate all my Cheetos".
Daddy: "I remember when that happened. You were crushed."
Timmy: "I still am."
