I'm honestly curious.
Part of my job involves giving trainings, sometimes in workplaces, sometimes in adult education classes. They last for a full or a half day.
I don't really stand on ceremony, of course. I tell people if they want a bathroom break or a cup of tea, no need to wait for the break.
Last week I was giving a training for volunteers at a particular organisation and one of the women up front took our her knitting just as I was beginning. I did a double-take and she noticed and said, "Oh, I always do this at presentations and lectures, it helps me concentrate." The people around her nodded.
I just shrugged and carried on. It was a good session.
Now if I were in a role of a long-term instructor or advisor or something I would have taken her aside and let her know how unprofessional it looked. But I'm not, it wasn't my place, so I didn't.
But AIBU in feeling really disrespected? My reaction really surprised me, because I don't think of myself as really rigid and uptight. And certainly I can listen intently to something whilst my hands are occupied--just listened to the radio whilst making jam, in fact. But it just seemed so damned rude. I had to really swallow down the urge to say, "Put that away, I'm not a TV!"
Would you have felt the same?
