renegade - a person who deserts a party or cause for another

A lot of people don't understand what it means to keep a promise. I have noticed that a lot of people are easy to pursue and convince. This trait isn't always bad, but when it means causing other people a hassle then it can be a selfish and rude thing to do. Renegades who consider their presence as a mere honor to their hosts are the worst kind of ingrates. Not only are they insulting the hosts of the original party by simply leaving, but they also are stating that they aren't interested in their surroundings and aren't enjoying their time.
