Here is my reasoning:

1.  Coffee cups usually become the center of conversation.

They are undoubtedly pretty and clever.

if not, they are at least acknowledged.  ”ohh, you have coffee. I need some…” That is surely more notice than a cup of water. And how many cups of water have you seen that say “I’m hot” or “drink me up”? Never.

2.  Coffee cups get the most attention.

If I’m eating dinner, my cup is functional, and it may get a solid 30 minutes out of the cupboard.
Not so is the coffee cup.  I purposely draw out my coffee cup experience as long as possible.  It’s affectionate and we’re somewhat attached.

3.  Coffee cups get to go sight-seeing.

My coffee cup is my backpack’s best friend.  It gets to go everywhere– class, work, car, etc.  Okay, maybe those aren’t the most exciting places, but then again, compare to the alternative:  the inside of a cupboard.

4.  Coffee cups have cool friends.

Common Groundians are usually hip, humanitarian aid activists wearing a beanie, big glasses, and TOMS with messy hair and ride antique roadbikes.

Starbuckics are the intellectual, talkative types over at Truett who casually comment on the classical music or Frank Sinatra and explain how both remind them of systematic theology.

AWESOME friends.

5.  Coffee cups see the world become a better place.

Usually grumpy people pick the cup up, but by the end, coffee cups have transformed Mr. Grumpy into Mr. Happy to Face the World.  They must sleep well at night.

6.  and lastly, coffee cups get hold coffee. mmm coffee.
