These days we have so many different ways to communicate that some people no longer call their friends when they have something to say.
Instead, they text, leave voice notes or Snapchat their nearest and dearest.
But there are still those who prefer to do things the old fashioned way and speak on the phone.
If you get a call and find the conversation particularly awkward or don't recognise the number but feel pressure to answer - then one woman has a solution for you.
A woman has shared a 'genius' life hack for smartphone users that will help you get off the phone very quickly.

The trick was previously shared on the YouTube series, Unfiltered with Zane and Heath, by social media personality Victoria Rose, known online as Woah Vicky.
The clip from the show has resurfaced online once more and many people are still learning from it.
In the video, Vicky's phone rings as she's talking to the hosts, she admits she doesn't know who it is calling but reluctantly answers.
She says: "Oh wassup."
Vicky then starts to say something else, but while she's talking she can be seen swiping on her screen, switching her phone to Airplane Mode.
"I do this to people when I wanna hang up," she confesses, showing her phone screen.
She explains that by turning airplane mode on, the call is disconnected and a message is sent to the other person saying "call failed" instead of "call ended".
So it looks as if Vicky was cut off, not like she hung up on them.
"That is genius," proclaimed one of the guys.
Vicky nods, adding: "I always do that. It will say reconnecting."
But the sneaky part is that it won't reconnect.
More than 12 million people have since watched the clip, with it garnering over two million likes on the @unfiltered account.
One person replied: "Most useful thing I have learned SINCE school."
Another wrote: "Wait that's actually so smart!"
"This is freaking good," proclaimed a third.
Someone else added: "No wayyyyyy, I'm learning from her better than my teachers."
