Mummy loves you, Afzal, always!

Last night, despite my coarse voice, I read 'Cat in the Hat Comes Back' to my little koala, Afzal. He loves the book and he wanted me to read the Cat in the Hat again after that but I just couldn't. My throat was bad, I was groggy from the medication and really zonked out. But as usual, my dear son, don't seem able to take to my reasoning well. I was so overwhelmed with anger ... i just snapped and he cried and went to sleep with his nenek. I really felt bad, because this boy is really interested in the book and the reading, and here I am doing this. Am I a bad mom?
