M: Yeah, but he's not as energetic as you are. Well, no one is. But the boss doesn't blame me when I get a bit behind. He is very understanding with me. But with Jim, he goes on and on. W: I haven't noticed it. But you're probably right. I wonder why he does it. What was said before this conversation?
Answer:
W: I don't know what Jim's got to grumble about. My work load has doubled in the past year and I still manage. He is not doing anything different from when he arrived, as far as I can see.
