That I had unfollowed them. They realized it had to be a mistake, because we were in the midst of an active conversation. Tumblr unfollowed another friend for me too a few weeks ago. On top of that, I updated my Tplus app, and the new version won’t let me comment on likes anymore. Way to ruin my interactive fun. Why would they do that?
So if you notice I’ve unfollowed, drop me a line and let me know.
