My 12-year-old daughter just walked into my office, carrying a cup of coffee. That she made for me. Herself. Without me needing to lift a single finger.
[Edited to add: It was decaf, and she also made one for herself. Which makes this even more awesome...because I can count on it happening again, and often, since I don't have to wait for her to want to 'do something nice' for me. Her already-burgeoning love of coffee is going to make my life so so so much better.]
