With so many of us communicating with via email and text message, the hand-written thank-you note has become a bit of a rarity. But good manners go a long way. Put pen to paper to express your thanks the old-fashioned way—for the birthday gift, the dinner invitation, the favor, or the simple gesture of kindness that made your day. Use your handwriting and full sentences (and recycled paper!). Bonus: Your expression of gratitude will make your recipient feel even more appreciated.
