My grandparents got married young (one grandmother at 18, one at 19, and my grandfathers are 2 years older than them) and my parents married young (my mom was 20 and my dad was 22). Whenever I have a boyfriend, one of my grandmothers is always asking my mom if "he's the one." And I had a boyfriend over Thanksgiving but we just broke up, so that should be fun explaining that to the entire family over Christmas.
But my sister is 23 and not dating anyone, so I think I'm in the clear for awhile.
