RTE's Ryan Tubridy has admitted that he's forgotten how to greet people after he met someone in the supermarket.
For over a year in Ireland, people have been practising social distancing and not shaking hands with others.
Last year the head of the US COVID-19 Taskforce, Dr Anthony Fauci, said he did not see people ever shaking hands again.
Close physical contact with people outside your household is still not advised by medical experts.
Tubridy met someone he knows quite well in the supermarket but wasn't sure what greeting he should use.
He told listeners on his RTE Radio One programme this morning: "I've also forgotten how to greet people.
"Because of the nature (of the pandemic) , we don't know what to do, to shake hands or hug or what.
"This person I know very well, my instinct action would be to go in and I forgot.
"It was the first time in 18 months.
"I was in the supermarket, sorry.
"It's been a while, I was only thinking last week, I'm actually missing the handshake which is a strange thing.
"Initially I didn't mind it so much.
"I was always a fan of hand sanitiser not neccessarily as a germaphobe but as somebody who likes clean.
"The handshake is a nice ice breaker to say hello to somebody."
Tubridy feels that a lot of people have forgotten how to dress properly but joked that he doesn't include himself in this.
He added that they are also comfortable to eat on Zoom calls in front of anyone else.
Ryan said: "No one irons their shirt for their housemate.
"Pajamas on the bottom and shirt on the top.
"Zoom uniform now feels perfectly professional.
"Some people are happy to chomp into a sandwich mid meeting or get stuck into whatever meal they heated up from last night.
"This destroys the microwave and people's sense of smell around the kitchen.
"We've forgotten how to dance and forgotten to plan.
"The first invite to a party will be a surreal moment and we expect sales of diaries to rocket.
"My calendar is as empty as the day is long."
