Here is something that I really hate:
SL is full of actual people. SL is not the Sims. So it bothers me intensely when RL thinks they can walk into or phone into my time and expect me to immediately stop SL and turn my full attention to them.
Please! I am in a room with friends. I can not, and will not walk out of the room without so much as a goodbye and in some cases, I will not walk out of a room of my friends if it not is the right thing to do under the circumstances.
SL society and social situations are real.
