My mom and I went to the store. She and I bought a lot of things for the school. When we came for the office, I looked very much for it. Because there were some very cool things that I wanted. And I wanted to see back but there was no mom. I was very scared. But I found my mom at the checkout. And my mother told me that when you looked at the pens there, I already bought everything. And I was offended. But I told my mother that I am a loss for you and mom laughed very hard and said that you didn't even recognize your mother
