I saw these quotes on someone's profile and they're cute:

"When someone loves you, the way they say your name is different. You just know that your name is safe in their mouth." Billy -age 4

"Love is what makes you smile when you're tired." Terri -age 4

"Love is when you tell a guy you like his shirt, and then he wears it everyday." Noelle -age 7

Little kids totally have a way with words. =)
