That stings, somewhat.
In 2014, the University of Colorado Denver conducted research into the act of unfriending via Facebook.
The studies published found people were most likely to unfriend others who shared polarising political or religious views, or if they found their posts uninteresting.
Respondents' reactions to being unfriended ranged from shock, to discomfort, to visceral sadness.
I think part of the reason being defriended hurts is because we have become so reliant on social media to maintain our relationships.
Many facets on our lives are conducted on Facebook. Businesses are opting for a Facebook page over a website. News outlets use it to publish their lead stories. We make a "Facebook event" to organise a birthday party, or even a wedding, where once we sent invites in the post. We use it to show off travel photos, announce our engagements, update family on our kids' milestones.
And we use Facebook to keep in touch with friends, particularly those who live in different parts of the country or overseas. These days, many of us find ourselves either too broke for long distance calling, or too exhausted to write an email. So we make a Facebook post, and our mates all over the world know what we're up to.
But when we become dependent on the internet to keep our friendships afloat, it makes it all the more real they are ended online. If our connections are mostly upheld and continued using social media, then being dropped via Facebook tells us the person wants no more do to with us.
In many cases, pixels on a screen is the only contact we have for some people so, without a phone number or address, the connection is lost.
Positive though Facebook can be, the internet is no substitute for a hug from and coffee with a friend. Personally, I need to make it a priority to step away from the computer. Send snail mail letters, take more trips home to Wellington, or simply pick up the phone.
Sometimes, "kicking it old-school" isn't such a bad thing.
