Lazy

No, I am not talking about me. Although I think that sometimes I am lazy, I am just good at putting things off, I think. If something really has to be done I get it done. At work, I always get things done ON TIME.
We do have to monitor telephone calls here and so we have to make sure that always enough people are available. Well, when you're on the phone, you're not really available, right?
So, why do some people have to talk one or sometimes even TWO (!!!) hours on the phone?
That is rude and inconsiderate.
Maybe I should just leave and come back 30 minutes before it's time to go home. Thats about the same.
