To me, coffee represents bitterness, which also means you're an adult, no longer a child. Further, each coffee has A DIFFERENT TONE AND FRAGRANCE; WHEN YOU TASTE IT, YOU WILL DISCOVER IT FROM THE FIRST, MIDDLE, AND LAST TONES.

Coffee shops also have dessert. when you have a cup of coffee, you must want some dessert with it, and it is the best match between sweet and bitter.
