Echino- What?

May 16th,  2014

Thursday was a very laid back kind of day. I had class in the morning and early afternoon. It was such a beautiful day that I ended up spending the rest of the afternoon outside reading my book and napping. When dinner came around Nick convinced me to get pizza with him and Will and then watch a comedy show. Before we left I had to test my new camera and get a picture of the beautiful sunset.

Then it was time for a bit of studying before bed. Overall, it was a very easy, relaxing day.

Friday, the last practical class of the trimester. It started off with our usual quiz then off we went. The phylum we were looking at today was Echinodermata.

When I got back from class I dragged Nick out of his room to play tennis for couple hours in the beautiful weather. Right after we got done playing I got the call that my new underwater camera was in. Nick and I picked it up and ran to the store to get him groceries. The rest of the night I relaxed watching some shows, until Nick scared me. I had just finished making popcorn and walked into my room. He was hiding under my desk and jumped out. He was so lucky he didn't get a glass of water poured on him. I calmed down eventually and went to sleep.
