I've been in 3. My brother's and good friend that I've known since preschool, and my sister's. My sister is having another wedding because her first was just a quickie and they want something bigger so his family can be there too, so I'll be in her wedding again in July. Does that count as 4?

I'm not the biggest fan of being in weddings. It's a lot of money and work, and I'd really only want to do it for my nearest and dearest, which luckily that's all I've done.
