The memories and joy that you have brought to our daughter’s life is priceless. When she grows up, I would want her to be like her auntie – beautiful and strong. Happy birthday, my sister-in-law!

With the sun shining and birds singing to match the smile on your face, I send my wishes dear sister-in-law.

Thank goodness you married my brother, because now you can take over the job of spoiling your nieces and nephews. He does a great job, but I know that you are going to be even better at it because I’ve experienced being spoiled rotten by you first-hand!
