Who: Friends and family. (If you think you are, you are.) What: Schnee-Weasley wedding. When: Backdated to Saturday, August 5. Where: The park. Warnings: Likely (hopefully) low.
Fred couldn't believe this day had actually arrived. He had asked Weiss to marry him years ago, and while she had said yes, she had requested that they not marry immediately. Fred was more than happy to oblige -- he didn't want Weiss to do anything she wasn't ready for. She had apparently wanted to marry Fred, she just wasn't ready to do so at the time of his proposal. Which was completely understandable, and Fred had been more than willing to wait as long as she needed.
Now seemed to be the perfect time, though. George was here, and friends from Weiss's world as well. He wished they had been able to marry while Ron was still here, but he knew he couldn't have everything. At least he had his twin brother there. His best friend, his best man. That was important to the Weasley.
The wedding had been a small one, but it was perfect. Weiss and Fred hadn't needed anything too big or extravagant -- as long as their friends and family were there, that's all they needed.
