What to write in a wedding card

They grow up so fast… I can’t believe you’re grown enough to actually get married. I guess I still feel like a five-year-old. But even my five-year-old brain understands that it’s a huge step for you, and I’m extremely excited. I’ll be there for you if you need anything. Congrats!
