IN RL people tend to do this "not focused om RL"
In SL we have the IMs that take our focus away. It can also become rude if you havent agreed on how to handle this. Its difficult to stay in focus if you are answering IMs all the time and on the other hand if you dont answer IMs then that also could be rude.
You smart people :-) How do you handle this ?
Look forward to hear your smart ideas/thinking ;-)
