Isn't it ironic?

Apparently, I am not a strict enough mother. How do I know this? My 4 year old informed me.
We use a discipline chart at home that is similar to the one at her preschool. Last night, I had to change Genevieve's "green card" (which is a good color) to a "yellow card" which gave her a 5 minute timeout.
This morning, as she is getting ready for school she informed me that I don't discipline correctly. She said, "At school, Mrs. Sullivan only gives us 1 warning and then changes our card, but last night, you gave me like 3 chances before you changed my card!"
Isn't it ironic that her honesty is now going to cause her to get stricter punishment?
