i wanna marry you because you're the first person i wanna look at when i wake up in the morning, and the only one i wanna kiss goodnight. because the first time that i saw these hands, i couldn't imagine not being able to hold them. but mainly, when you love someone as much as i love you, getting married is the only thing left to do. so, will you, um marry me? - Will Hayes, "Definitely Maybe"
For in-laws... I know this is meant to be given as a gift for a wedding but I think it would be ok to give anytime. A Dad (or Mom) want to know that they have done a good job parenting and hardly ever hear it said.
