The Boat to Fuerteventura

Two summers ago, my friend Jose and I had tickets for a water park in Fuerteventura. We decided to take the early boat to have more time during the day and be able to go shopping.

When Jose and I arrived at the port, it was crowded. My friend said, “If we had come earlier, we would be the first ones here.” During the trip, Jose got seasick and vomited on me. I told him, “If I had known this was going to happen, I wouldn't have sat next to you!” As soon as we arrived in Fuerteventura, we went straight to the water park because it was scorching.

We had a fantastic time at the water park. All in all, it was an unforgettable experience, and I would definitely repeat the trip.

Josemaría and I were very good friends since our brothers went to class together. He and I were like brothers, we went everywhere together, and the whole school knew us. Some said he was my boyfriend, but he and I loved each other like brothers. Our fathers had worked together for many years, and our mothers were close friends, like our brothers and like us. Every day we saw each other at school, and some weekends we spent together at their house or mine since our parents would meet for dinner together.

When our brothers grew up and changed schools, they stopped being friends, but Josemaría and I were still as close friends as we had always been. After a while, when I changed schools, he also changed friends, and we stopped being so close... Continue reading "Close Friendship Story: Growing Apart Over Time" »
