Up until I was like 7 or 8, I thought the lyrics to the song "Last Christmas" were, "Last Christmas, I gave you my harp..."
A childhood belief about misheard lyrics

others believed things like this
- I was told that for every christmas carol i sang before christmas time santa would give me one less present!— K
- I use to think the known Christmas song "in excelsis deo" was en chelsea's dayo— Mike Simmons
- when i was little i thought that jesus delivered presents on christmas not santa .— gaby
- I used to think that partridge in a pear tree was "cartridge" in a pear tree(christmas song)— Erica
- I didn't know Reindeer existed, I thought they were just christmas animals for storiesAnon
- When i was little, I used to send Jesus birthday cards on christmas and thought he would read them in heaven.Anon
