Question For Those Who Are Married

I am not married but my grandparents have been married for 50 years this past October and they're very much still in love. My grandfather still buys my grandma a bouquet of 2 dozen red and white roses for Valentine's day. He also does what he calls "his maidly duties" every day for her. He says she creates a mess so he can clean up after her. hehehe. She just tells him that's she's not messy because she's intelligent and creative and what he calls a mess is just a by-product of her genius.
