I knew a girl like that once. She asked her boyfriend to marry her, in 5th grade (around 16-17 y/o). As far as I know they're still together. Did I mention that they were together then for about 3 months? And that he lived on the other side of the country? And they met on summercamp? She took the train to go see him for a weekend, and asked the guy to marry her, not with rings, but with a necklace.
