Usually wedding gift options are pretty limited (stick to the registry!), but sometimes it's OK to pick something out of the ordinary.

That's just what one thoughtful sister did when she gave her brother a priceless note as his wedding gift. In a post on Reddit, a user explains how his best friend's sister saved the "I hate girls" note the groom composed when he was six, and framed it for the groom's wedding day.

The groom, who also happens to be a Reddit user, recalled the "epic moment" he opened the gift on his wedding day: "Not til (sic) she pulled that out did I ever remember writing that," he wrote.
