I used to believe that the lyrics to "Mothers Talk" by Tears for Fears started out "My peaches fall with the change in the weather" but in actuality its "My features form...". It took until like 2016 before I realized this.
A childhood belief about misheard lyrics

others believed things like this
- I was 14 when i realized that nectarines were not shaved peaches— tim
- I thought weather forecasters were psychic and that's how they knew what the weather would be.Anon
- That only men farted. I literally started sobbing the first time I realized I farted.Anon
- Actual lyrics: "I've never been your beast of burden"
My lyrics: "I've never been your big suburban"
— Big Suburban - I used to believe rain were God's tears— Joy
- I used to believe that I could control the weather... I had limited success— Mark
