Mug life

What makes a coffee mug so special? Is it because of the way your fingers slip into the holder so nicely that you FINALLY feel you're in control? Or is it because the coffee inside makes your day, if not somehow makes you get through the day? Or does it have something to do with the stains it quietly leaves behind? Did we choose the mug life? Or did the mug life choose us?

I really don't know the answer.

My best guess is a coffee mug is somebody who stays with you through your highs and lows.
