When all you have ever known is touchscreens and smartphones, a rotary dial phone might as well be from the Moon.
Teenager Braylon Daigle proved this once again in a viral video shot by his mum, 39-year-old Kimberley Phillips.
Phillips encourages Braylon to try and call her on an old-fashioned rotary dial telephone and it does not go well.
First he begins by dialling the wrong way round, sticking his finger in the zero hole before spinning the dial to the number he wants.
As those born before the age of the mobile phone knows, you are actually supposed to put your finger in the number you want and then rotate the dial round to the metal catch.
