I used to believe that there were only office buildings in Manhattan and only zoos and farms on Staten Island.
A childhood belief about places

others believed things like this
- I used to think 'To Let' on disused office buildings meant they were big toilets.— Tracey
- I knew that dairy farms have silos so I figured that they're where the milk is stored.
— marianne - My Dad told me that the big bales of hay wrapped in plastic sitting in the fields on farms were cow eggs.Anon
- I used to think that Alaska was an island!— Draqula
- i used to believe that scaffolding was used to support buildings when they were having work on them.Anon
- i used to believe that 'island' was pronounced 'is-land' instead. I know im not alone on that one! :)
