On top of overfamiliarity, intimate friendships can also face challenges when it comes to lack of third party support.“I think the benefits of the one-to-one friendship is that you get to focus on each other, but with that being said, you have to face each other,” says 23 year-old writer and barista Melina Cavella, who met her one-on-one bestie a year and a half ago at university. “There’s no third or fourth friend to run off to when you want to avoid a problem or get something off your chest.” This confronting honesty is something 38 year-old freelancer Lianne Bell, echoes, having been friends with her one-on-one bestie since infancy. “I think you can’t hide with one-on-one friendships. If you’re an absolute dick that person is gonna know and they won’t stick around,” she explains.
