If you've somehow missed this over the last couple of years, there is a man from Virginia called John Lewis (@johnlewis) on Twitter, and there is a British department store called John Lewis (@johnlewisretail) on Twitter.
Every year, John Lewis (the store), does a heartwarming Christmas advert that sends Britain into meltdown, and every year people struggle to tell them apart.
He is an extremely polite, patient man.
Every year, he calmly directs each person who mentions him back to the department store.
And this year's tearjerker is a powerful advert about how elderly people face loneliness at Christmas.
Which was immediately top of the UK's Twitter trends.
