This is the 42nd World Hello Day which is an attempt to promote peace around the world.
And if you think that’s a bit ambitious, I should add that it’s supported by 32 winners of the Nobel Peace Prize.
The principle is that if you are speaking you are not fighting. As Winston Churchill said: “To jaw jaw is always better than to war war.”
When you think about it, they could be the lyrics from a Beatles song.
The four mop tops (and how long is it since you heard that description?) did their bit for world harmony, most famously when they took part in the first global television link in 1967, and sang All You Need Is Love to 400 million people in 25 countries.
Mick Jagger, Keith Richards and Keith Moon were among the celebrity audience singing the chorus. Ah yes, I remember it well. I was not invited.
Hello Day is more of a grass roots effort, an out-reach of friendship, where the organisers urge everyone to say hello or give a good day greeting to at least 10 people, maybe even a stranger or two.
So try out an ‘ow do, bonjour, gutentag, hola, jambo or a simple hello, and get at least a small part of the world talking to each other.
Of course, in today’s social climate and changing mores, it might be best not to approach young ladies with the sort of lecherous “hello” that Leslie Phillips perfected in Carry On and Doctor films, unless you want to get arrested.
