Hung up on

Of all the antiquated terms people use, I find “hanging up” the phone to be the most amusing.
We used to hang the receiver on the phone to terminate the connection.
Now, it’s a button on a cell phone.
Although pushing a button to cut off a call, depending on the type of phone, that’s been around a while.
Picking up a phone to take a call isn’t always necessary.
When we have headsets and speakerphones and car phones, we don’t actually pick up the phone.
And illegal, when you’re driving.
But I guess hanging up is my biggest hangup.
