That's That Me Espress…oh
Riddle: You place a cup of coffee in front of your friend. You then ask your friend, "What's before you?". Your friend answers, "Tea,". Why is this answer correct?
Answer: If the answer to your question was "coffee", you would have never asked such a simple question. In fact, the question and answer were a play on words; you were asking your friend what comes before the letter U (you) in the alphabet. The letter T (tea) comes before the letter U, so your friend's answer was correct after all.
