A husband and wife decide on a code

 

However, the husband misunderstands that it was a deliberate excuse on her part.

Next day the son comes to his dad on an errand from his mom this time and tells him, “Dad, mom said it is okay now; the red ribbon is removed and you can type.”

The husband then tells his son, “Tell your mom I don’t need to type now.

It was urgent, so I’ve already written with my hand!”
