If you've been holding a grudge, Friday, Aug. 25, is the day to let go of it. It's National Kiss and Make Up day.

The day is celebrated by — you guessed it — letting go of any arguments and making up.

Some other quirky, delicious or otherwise fun and interesting observances Friday:

  • National Park Service Founders Day
  • National Whiskey Sour Day
  • National Second Hand Wardrobe Day
  • National Banana Split Day

So dress up as Second-hand Rose and have a whiskey sour and kiss someone you were at odds with recently. Visit a national park and eat a banana split!

Enjoy the day.
