So a blonde was told by her husband that saying good morning is a very polite thing for people to do. So the blonde goes out on the street to see if people would say good morning to her. When she returns to her apartment 20 minutes later, her husband asks
"how did it go?" The blonde replied "horrible, no one sayed good morning to me, I dont understand why, are they all just rude?." The husband looks at her in her eyes and replied "No, its because its 8 o'clock at night."
