I know being friends in social media don't equate to real friends in life. However I noticed a trend. Several people I hangout with on a regular basis unfriended me on Facebook. I can't help but wonder why. I still see them regularly. In fact one of them was the one who took the picture I use for my profile. I don't use my real last name and was wondering if my profile is coming off spammy? We certainly have used Facebook e.g. chat messages and invited each other to events. I guess now days there's nothing you can do with a non-friend as you could with a friend on Facebook.
What's the best way to casually approach this with out making the situation awkward and allowing them to be honest?
I'm thinking "hey I noticed we're not friends on Facebook anymore, did you realize we got unfriended?"
