Neil Patrick Harris's daughter wrote an adorable letter to the tooth fairy

I wish all mail was this cute.

Neil Patrick Harris posted a photo to Instagram Friday of his daughter Harper's most recent correspondence with the tooth fairy. Predictably, the letter is adorable — the seven-year-old announces that she has lost a tooth, then tells the tooth fairy, "I love you because you rock!" As someone who receives primarily Bed Bath & Beyond coupons in the mail (NOT a complaint), this sentiment has deeply moved me. 

Harper also utilized a variety of crayons to create her masterpiece — a sign of carefully considered design. There's even a wonderful tooth drawing.
