When I was in the process of learning how to read a clock, I thought that whatever number the second hand was on, that was how many minutes after the hour it was. Like if it was 1:20, I would think it'd be five after one.
I was corrected very quickly about my thinking.
A childhood belief about general

- I thought the big hand was for the hour and the smaller one was for the minutes until i was in third grade.— Time Challenged
- I used to believe that a quarter after the hour was 25 minutes after the hour because 25 cents = a quarter.— Marni
- If you pulled a face, and the clock struck on the hour, your face would stay in that position.— Jo V...NL
- I thought that a quarter hour was 25 minutes long, since a quarter was worth $0.25.— Crystal
- When I first started learning to read I was convinced that vowels were called barnacles.— Andy Howell
- when my friend was little, she used to eat paper, thinking it would make her read better.— hehehe
