Mad props to the polite

Okay, here we go. I had to try really hard this week, but here's what I got:

• A nice threesome of diners leaving a waitress a 20% tip.
• People holding the elevator for one another.
• Drivers who were let into traffic who actually raised a polite hand and said, "Thanks!"
  

Thank you, polite people! You make all the noisy, inconsiderate jerk-offs in this world not matter so much.
