Pria recently hosted her friend$$s bachelorette party, which was an adventurous backpacking trip through the Grand Canyon. Everyone at the party had a great time. When they returned from the trip, Pria posted pictures of the event to Instagram so that all the attendees could see them. What she had not thought of was all of the colleagues in her Instagram network who could also see the images. She had called in sick to work for the first two days of the trip, forgetting that her colleagues may see the images. What is this an example of$?$
