As the big sister, and one who is slow to appreciate change, I wondered how I would feel when this happened. Well here's how I feel: I am completely excited and happy for the two of them. I am looking forward to getting to know his fiance better over the years. I will admit that it is hard for me to recognize that he is actually old enough to be getting married, but I will be praying for them as they begin a new, exciting phase of life.
Congratulations to my brother and future sister-in-law!
