When my sister was around 7 or 8 she was invited to a birthday party. The invitation stated "The fun begins at 5:30!"
On the day of the party, it was getting close to 5:30, and my sister complained to my dad, who was dropping her off at the party, "Daaaaad, it's 5:26, the fun's gonna begin in 4 minutes!!!" She believed that the fun literally started at exactly 5:30"
