I was born in the countryside, where people did not have mobile phones or tablets like people in the city. However, I have many happy memories here. One (that) I distinctly remember occurred about ten years ago. One day, some friends and I went for a walk near a huge field. We were so curious about the world beyond our street that we walked through/across the field and played on the other side, not caring about time. Our moms were worried and tried to find us. After 30 minutes, we realized it was late. We went home in fear. My mom scolded me for a few seconds, but soon afterwards she hugged me and was grateful that I hadn’t had any problems. Although it was my fault, I was happy to know (that) my mom loved me so much. ^_^
