One of my colleagues came to my office to chat, and I was busy on EC. He thought I was chatting on an online chat room again, but I told him that I'm busy on a forum. I almost said LGBT forum, but luckily I didn't. It would've been very awkward. He's a very religious person, so I doubt he'd take it well. I'm only out to one colleague, and I don't think he really understands what it's about...
I use EC on my iPad when I am on my breaks at work and I am always constantly worried someone will come and look at the screen unintentionally. I think I guess just be careful when your online during work time.
