Busy!
Most couples apart committal you to answer "congratulations" when they influence busy. Provided you hunger to moxie also and lay it in verse, there are some websites and other sources outside there that encompass poems that might be prerrogative for the case.
Instructions
1.2. Discharge some check at Hallmark or another alms card store. As corny as it may sound, the card verses are written by professionals trained to find those "right" words. You could find just the right poem for the couple in mind.
Search some websites that bull's eye on poems of romance. Some are listed in the references divide. For another, search using keywords such as "engagement sayings." Jab other keywords related to congratulations cards or still engagement announcements. If that fails, spend some time in the poetry section of a book store or library.
3. Check out some lines from the movies. A quote from a movie may seem corny, but it can be extremely personal in an engagement congratulation letter or card. For instance, "Sleepless in Seattle" has the famous love quote:
"It was a million tiny little things that, when you added them all up, they meant we were suppose to be together... and I knew it. I knew it the very first time I touched her. It was like coming home... only to no home I'd ever known... I was just taking her hand to help her out of a car and I knew. It was like... magic."
If that's too long, there's always "You complete me" from "Jerry Maguire."
