Heard this morning on 102.5 The Bull, one of Birmingham's Country Stations:
Patty: Today is National Pay a Compliment Day!
Silence. More Silence.
Patty: I like your clavicle.
Bill: Um...you have a very nice Adam's Apple for a girl.
After another brief period of silence, they both burst out at almost the same time:
What were you waiting for? Followed by... I was waiting for you to give me a compliment!
Haha. Patty noted afterwards that compliments have fallen by the wayside to some degree, and encouraged everyone to pay a compliment to someone today.
So, there you have it. Go forth and compliment. It will make you feel happy, and when well spoken and said from the heart, can make the receiver feel marvelously happy as well.
