I like to stare at old people and wonder what they might have looked like when they were young

You know that feeling, when you're having something delicious after a long hard days work? That most vibrant and rejuvenating and most perfect feeling of satisfaction when you deservingly take a bite into your fresh warm food. 
And then mid way through this matchless and divine moment something important comes up and you have to leave immediately. You're forced to keep the food aside till your work is complete. Deep, sorrowful music plays at the back while a crestfallen tear trickles down your heart as you reluctantly step away from your wholesome God.

You can't work straight. The taste of the unfinished, tender food lingers in your mouth.
The food gets cold. The work is left incomplete.
