We say it to cashiers, neighbours, colleagues and strangers.
Most of the time we forget the exchange almost immediately.
But the meaning of a greeting changes when somebody has made a special effort to ensure that you can receive it.
Tallulah could have assumed that because Tim could not hear her spoken words, meaningful conversation was too difficult.
Instead, she changed the language.
That tiny adjustment communicated something beyond the literal words.
It told Tim that he was worth making an effort for.
His response told Tallulah that her effort had succeeded.
And then he gave something back by teaching her another sign.
The Story Continues to Mean Something
More than six years after the original video appeared in 2020, Britain has taken further formal steps toward recognising and expanding access to BSL.
The British Sign Language Act now legally recognises BSL in England, Scotland and Wales.
Government departments have reporting responsibilities relating to the use of BSL in public communications.
And the development of a BSL GCSE has created a formal pathway intended to allow more young people to study the language in school.
The government's own rationale for the qualification includes the hope that more people will be able to use BSL in social and working environments.
That gives Tallulah and Tim's little conversation an interesting resonance today.
In 2020, Tallulah did not need legislation or a qualification to understand the basic idea.
She saw a communication barrier.
She learned a few signs.
She tried them.
Tim smiled.
Then he taught her more.
Sometimes Inclusion Begins With Hello
Perhaps that is why millions of people responded to the video.
The story did not involve money.
Tallulah did not buy Tim an expensive present.
She did not organize a campaign.
She did not perform some enormous act of sacrifice.
She simply took the time to learn how to communicate with another human being.
And Tim responded by welcoming her effort and helping her learn.
In a world where differences in language, ability and experience can sometimes push people apart, their interaction demonstrated the opposite possibility.
A difference does not always have to become a distance.
Sometimes somebody simply has to make the first effort to cross it.
For Tallulah, that effort was learning how to say:
"Have a good day."
For Tim, it was answering her — and teaching his young friend what she could sign next.
Their conversation lasted only moments.
But millions of people understood what it meant.
Sometimes kindness really can be that simple.
