It's not that good by an example can be...
Dear Diary,
I remember when I was 8 years old, my parents took me to the zoo for the first time. I was thrilled and amazed by how many different animals there were. I can still remember how fast my heart was beating, and how many times I got scolded for running off, because I wanted to see another creature such as a giraffe. 
The next most exciting thing after entering the zoo was that I was allowed to pat a lion cub. It had golden fur which felt smooth to touch, and pointy whiskers that poked my skin. After that I had small pink bumps on my arms from the times when the cubs whiskers had poked me.
I loved that day so much that when it was finally time to leave I was reluctant to go and threw a small tantrum, which washed away when my parents promised to take me again. So, that visit to the zoo was the most memorable day of my life, because of how I felt.
