That is how dictionary.com defines a friend. But I have a few more. Loves you, your husband and daughter. Plays you in scrabble. Compliments you. Reads you stories. Listens to Frog and Toad stories (requests them, actually.) Sings with you. Makes you laugh. Laughs at your jokes. Understands you and your problems. Shares her joys and troubles. Heeds your advice. Gives you advice. Gifts things upon you. Memorizes Bible verses with you. Shares with you from her abundance. Watches movies upon movies with you. Plays card games with you. Is working on being a better loser with you. Cuts your hair. Will change stinky diapers and soothe a cranky baby. Cooks the most delicious food. Is willing to eat pizza with you at every meal. Is a sister to me.

I have a friend like that.
