      Today I went to the beach. It was my first day at the ocean for many years. The sound and smell of the ocean brought back memories of the great family vacations when I was a child. We always went to the beach for a week in the summer. I remembered playing for hours in the sand with my sister and crying when I couldn't have any ice cream. Oh, and I remembered finding a huge jellyfish on the beach, and running away because I was scared! Amazing, really, the things you remember from your childhood...

    Yeah, I remember going for long walks in the countryside. I guess I was only eight or nine. In the winter, my mom made soup, and I can still remember the wonderful smell! When we got home, I always went straight to sleep...

    What a great story! I remember going to the beach, too – on Christmas Day! My family lived in Australia when I was young. I remember waking up early. After we opened our presents, we always went to the beach and had a barbecue.

    The best memory I have is playing my first video game, Super Mario. I remember thinking that it was amazing, It was my tenth birthday and I still remember opening the box.
