Blessing in Disguise?

I had a friend with an overshare problem.  Not only did she overshare personal information, but she went crazy with reposting on facebook, and retweeting on twitter.  So much that I had to hide her from my facebook news feed, and turn off her retweets.  It was as if she was reposting every single thing that she saw.

Well, a few weeks ago, I decided to let her know that I turned off her retweets because I was getting so many retweets about Obama and Biden, that I may as well have been following them myself!  (Please note that any other subject matter would have been just as annoying, but because it was related to Obama and Biden, it became political...*sigh*)  For the record, I was polite in my message, just like all the other times I was polite to her even if she was being moody.

We had been friends for 2½ years, so of course I thought she would see the humor in it, and possibly even consider how many others she could be annoying with all of her superfluous postings. 

I was dead wrong.

She was so hurt and offended that she decided to stop being my customer, for both of my businesses.  She also even dragged my husband into the mix by saying she doesn't like all his posts about Romney but she doesn't say anything. What?  When did this become about Romney or my husband?  Also, that's what the "Hide" button is for.  I should know, I used it on HER!

I waited a few days before I replied to her.  I didn't want my shock to cause me to say something that I might have regretted.

When I emailed her back, I explained to her what I said above, that I would have been just as annoyed if the retweets were about the Steelers, or bunnies, or whatever.  I then provided the names of two other representatives, should she decide to resume buying in the future.  Lastly, I offered to mail her jewelry to her (which I am repairing) so that we wouldn't have to meet up again, since doing so causes her so much discomfort (her words).  I asked her to provide me with her address, and that was that.  I'll update on what her reply is, if anything.

One of the issues here is that so few people speak their mind.  So few people speak their mind, so that when someone actually does, it seems that they are being unreasonable.  I wish more people would speak their mind.  It doesn't mean being rude.  It can and should be done politely.

So you tell me, did she do me a favor and was this a blessing in disguise?  Or was I completely out of line?  Should I continue to voice my opinion, or should I keep my mouth shut from now on?

I welcome and appreciate your (polite) feedback about this incident.
