After a wedding, donate all the live flowers to a nursing home. Deliver them in person and try to personally give one to all the ladies that live there. Ask them if they have any marriage advice for you!
haha! Love life hacks, except the coffee shop one, where I worked we knew what you were up to and charged you for the large coffee (and if you were a dick about it, we'd under pour :P) ... Moral of the story: pay the 20 cents extra
