Nelly, I have to say I had so much fun writing mine. I'm a writer, so... poor DIAC. They don't know what lovey-dovey drivel they are about to have to read, haha. Definitely go ahead and include sentimental stuff, but also make sure you hit every point they've asked you to make as well, as Mark said. I think this is the fun part of the application! I enjoy telling people why I'm so crazy about my fiance... I can't wait to have an entire new continent of people to bore with stories about why I'm so crazy about him.
