I recall back to a memory of when I was 6 years old and I went kite flying with my mom and my cousin. She wrote down the details she recalled and ours differ a lot. We remember the same weather and the same setting. I didn't remember being with my uncle until she mentioned it. She remembers a lot more than me such as the colors of my kite and me liking it most when the kite flew around really crazily. I also didn't remember getting ice cream after kite flying and sitting on my mom's shoulders while my cousin was on her dad's. I remember being excited to see butterflies flying around and my mom didn't. I find it really peculiar though that I thought one of our kites got stuck in a tree when it really didn't happen. That's a good example of an existence proof. My mom clearly remembered more details than I did due to me just being a young child. I also recalled some events after my mom brought them up such as visiting the kite shop and looking at all the cool kites. It's weird how long-term memory works. Encoding, storage, and retrieval were definitely at work during this situation. I really wonder how exactly you would know the difference of forgetting a memory caused by retroactive interference compared to retrograde amnesia.
