In Antonia Nicol's case, her mom gave her dad explicit instructions to water the plants in their bathroom after she passed, which he kept up religiously.
Only to learn later that the plants are fake.
Before my mum passed away, she gave my dad strict instructions to water the plants in the bathroom. He's been religiously watering them & keeping them alive. They look so amazing he decided to take them to his new home, only to discover they are plastic! Can hear my mum chuckling pic.twitter.com/N87giD5zKT
