scuba diving

I had done scuba diving today. it's the first time to me so it's so impressive.
snorkelling too. Snorkelling was easier than what i expected but scuba diving had a big painful thing by press of water. when I went down in great barrier reef in cairns, my ears got terrible pain by pression of water. I felt like my eardrum was breaking so I wanted go up to surface of sea. but scuba was not cheap one to me so I decided to endurance a little bit more and I said myself 'my ears is fine' over and over. Finally my scuba diving time was over. I thought it's not short!! but the insde of sea was amazing I could not imagine before. I looked many colorful fishes, sea stars, a small shark, sea cucumbers and squids. how amazing the insde of sea is. after lunch, we had free snorkelling time so I worn snorkelling equipment immediately and started snorkelling with painful ears. I looked a huge clam size like tyre of truck. the master of scuba lead us said the one really massive one. after an hour, we wet back on boat. I got fatigue as soon as I got on the boat and I fell in sleep in the blink of an eye.
