F.O.L.O. (Fear Of Losing Orders)

"F.O.L.O." or “#FOLO” is an acronym for "Fear of Losing Orders". It refers to the emotions felt by people waiting in their homes for packages to be delivered. These emotions range from excitement and apprehension about when the parcel will arrive, to the boredom of waiting at home all day for a parcel, or annoyance as you stare out the window on a sunny day that you’re unable to enjoy.

Symptoms:

Fear of taking showers in case you miss the doorbell;

Incessantly looking through door viewer or window for delivery drivers;

Over-sensitivity to any noise that may resemble a delivery van;

Constant refreshing of delivery apps to check for updates.

Fortunately, there’s a solution for F.O.L.O. Systems like smart intercoms that allow people to answer their apartment intercoms from anywhere and remotely buzz visitors into their building with a smartphone.
“I haven’t left the house all day, I have major F.O.L.O. (Fear Of Losing Orders) ”
“My old intercom is giving me F.O.L.O. (Fear Of Losing Orders) ”
