My family and I got in the car one day when I was around one year old and headed to the beach for a nice vacation. Once we arrived there, we began putting down our belongings and relaxing for a bit on a towel. Then, we tried to find something do there. After, we played in the sand and made some wonderful looking sandcastles, although they didn't turn out that well when we finished. It was such a great time! We had a blast! "Let's go in the warm water," Dad said as we headed toward the refreshing water.

In the cool ocean water, we splashed around and played with each other. After a short while, my dad filmed a video of me strolling along the sand with my mom. Then, we played more in the sand and enjoyed the time at the beach. We relaxed a bit more on our towels and walked on the warm sand heading towards something else to do. After sitting under the hot sun, a bit more, we walked close to the ocean water one more time. It felt so refreshing and made the hot weather feel better.

Then, we saw this nice lady who was building a cool looking sandcastle by herself. I became interested in her work and ran over but I accidentally knocked over one of her sandcastles. It was our fault, and when we apologized to her for our mistakes, she said to us that she was okay with it, and it was alright. I started playing with the sand from the now demolished sandcastle that was knocked down and had a lot of fun. After we talked to the woman, we left the sandcastle alone and started getting ready to go back home when my parents said, “It’s time to head home now!”. We packed and gathered up all our belongings and headed to the car to get back home. It was so much fun while it lasted, maybe we should go again for another beach trip.
