AHW,Pine lake water skiing and wake boarding 2

It was my first day at the Pine Lake water skiing and wake boarding class. I said i wanted to use skis not a wakeboard. I was with my friend logan and two other kids a little bit younger then me. We started to get on the master craft boat. I was the only one out of the four of us using skis. I decided to go second,while my friend went first. It was a two hour period all together so each of us got 30 minutes but 15 minutes at a time. Finally it was my turn to go, I got on my water skis and jumped into the lake. When i got in i was just floating around, when they said "Cross your skis." i did that and grabbed the rope. "Are you ready?" my instructor asked, i said back "yes" And i started to water ski.  I could only hold on for a while before my hands got really tired, so i let go of the rope and relaxed in the water for my next run. After my 15 minutes were over i went back in the boat and waited for my next turn.  It felt like it had been forever since my last turn, but finally it was my turn to go back in the water. I put on my water skies and walked into the water. I started to float away from the boat, when they asked if i was ready, I yelled yes! back to the boat and i started to water ski again. I went through some bumps but stayed up.  My hands were getting really tired like the last time so i had to let go. A while after my turn it was time to go back to the docks because my class was over. My mom picked me up from the docks and started to take me home, she said "Did you have fun water skiing today?" I said "I had a lot of fun."
