As much as having to go to beaches and spend the entire time watching your girlfriend and her friends giggle in and out of boardwalk shops, thinking nothing's wrong while you begrudgingly pay for her 7 topping Fro-Yo SUCKS, these Facebook Friends by obligation are actually much better than the alternative–a girlfriend with zero friends is always a nightmare and a half. Or if they claim that ”girls suck,” and only hang out with the Bros. Cool for about two weeks, then a major red flag.
In conclusion, these people are the epitome of a necessary evil. Just remember to perfect your sneakily passive-aggressive “look how fake my smile is” teeth-clench along the way.
