It is my fault

It was 7:14 am and still dark. Jeff woke up to get ready for work. He said " hon, walang diaper si Yohan". I immediately got up and checked. It slipped my mind that she was wearing her undies the whole day. We put her on diapers when she goes to bed. This morning I whispered in her ears "Yohan, why did you pee in our bed? Well, it's my fault because I didn't put your diapers". With her eyes closed she responded by " it's my fault". I just said " ok " so she can continue sleeping.
