Love is shown in various ways, and some of those ways are surprisingly delightful. That's what happened with Antonio Nicol's dad, when he discovered a joke his wife left him from the grave.

Before his wife died, she gave him instructions to carefully take care of her plants. Antonio explained the surprising experience that followed in a Facebook post:

"Before my mum passed away, she gave my dad strict instructions to water the plants in the bathroom. He's been religiously watering them and keeping them alive. They look so amazing that he decided to take them to his new home, only to discover they are plastic! I can hear my mum chuckling!"

The gift of laughter

Antonio's mom understood the gift laughter gives in a relationship. According to a study, couples who share laughter together are better off.

"In general, couples who laugh more together tend to have higher-quality relationships," one of the study's authors, Laura Kurtz, told Time. "We can refer to shared laughter as an indicator of greater relationship quality."

Although they were no longer together, this couple is a great example of giving love on both sides: for him, he took care of her plants faithfully as she wished. And for her, she gave him the gift of laughter he likely so desperately needed.
