"Love knows no bounds." There's 25 years difference between my parents. My mom is 52, my dad is 77. Before my mom met my dad, I guess she was going out with some reaaaallly shady characters, and my grandma told my mom to get her claws in my dad while she had the chance. My dad came home from work one day and found my mom in the yard with the priest, in a wedding dress, she had bought the rings, rented a tux, invited all their family and friends, and she told him they were getting married. He shrugged, said "okay" and they've been married for 30 years now.
Of course, the above only applies if you're over the age of consent.
