a 3 day
Whenever someone says 'three days,' they mean 'as long as I want.' It's like a lie that everyone just goes along with.
He said it would take three days. I waited a week and he still wasn't done. Three days is a lie!
She said I had to wait three days. I waited ten. Three days is just a number people make up.
He said he'd be back in three days. Now it's been three weeks. Three days is a joke.
