Has anyone ever unfriended you without explanation? Did you ask why? Have you ever deleted someone from your friend list without saying why?
This is the Internet. Wank over being unfriended is completely unnecessary and asking for stupid drama.
I have been unfriended without it being explained and I have unfriended without explanation. Usually I unfriend a bunch of people at once, 5+ and so forth, and give a brief explanation on why the said bunch was unfriended. Something like "I unfriended some people whose entries I no longer really care to read" AND THAT'S IT, no need for drama, at least from my point of view. If someone asks why I unfriended them, I might give them a sugar-coated version of the truth.
If someone unfriends me, I shrug it off or force my self to shrug it off if the person who unfriended me is ridiculously important to me in a stupid, childish sort of way.
Reply to this post, and I'll tell you one reason why I like you. Then re-post this and spread the love.
But don't think I'll just give you more reason to be arrogant without you giving me something back. To get the love, you'll have to recommend a book or a movie or post a funny gif.
...I shouldn't write entries at 8am because I'm so weird and I can't write a comprehensible sentence this early. I'm also staying up until Friday because I'm the boss.
