Letter to son in "The Briefcase" story by Rebecca Makai as the professor. I wrote a paragraph but was wondering what all I can add to make it at least a page. We have to bring up past events but I don't know how to smoothly integrate them into the letter.

One time I was walking down Town and I could feel the wind in the trees in the breeze and suddenly I hear a sound I couldn’t quite put my mind on what the sound was but I knew that the sound was familiar. I ended up walking home after hearing that sound it made me uncomfortable but I know I heard it before. The sound was a high-pitched bell so that night I went home and told my mom about the sound she said you probably just heard something from the park down the street but I knew that sound, it was from when I was little. So I slept on it and then I remembered the sound was from the mill pond which is a park that I went to visit on vacation it has a musical section and I used to always play with those every time I would go to that park on vacation. when I heard that sound it just brought back so many memories. I could feel the high-pitched music note go through my body and trigger all the memories from when I was younger, and it just made me so happy and it made me realize that I may have grown-up a lot but the little kid that I grew up with is still in me and the memories will never go away.
