When we got married about 2 1/2 years ago, we put 3x5 cards on tables and asked people to write us a note with marital advice or similar. All of those notes are in a book now.
Tonight I was looking through it for something special to send to my DH in an email. Here are some gems from the kids.
From my SD now 16, 14 at the time "Dear Dad and Birdseed, Here is my advice to you...Love us 4ever."
From my SD now 14, 12 at the time "Don't have us clean our rooms too often."
"To DH and Birdseed, I am glad u got marriad. The wedding was rily fun. Love G" <--cousin, only about 5YO at the time.
"I hope u have a nice manje. love J. " <---twin to the above.
Then one unsigned card "Don't get married. Oops. Too late."
Just cracks me up.
