I invented the question mark.
????? Yes...That one <<
I was tired of asking questions with no inflection in my tone, so I basically sat down and said to myself "Self, you have to come up with some way of helping people discern when you are asking a question".
Within 6 months, I had invented the question mark we all know and love today. 🙂
It was hard work, but it was worth it.
I have also invented the Egg, the colour orange and the letter Q. 😖mart:
Have you invented anything?
