He is my favorite character on that show. He is what makes the show a whole lot funnier. I sometimes wonder if I will even bother watching the episodes without him on it. Though, he probably is exited to be with his faimly, so I am happy for him with that. He is my favorite actor, but he has a life too and he wants to spend it with his faimly and I am proud of him for that.
of course I'm sad! Steve Carell is the best and the core of the show, and I can't imagine what the show will be like after he leaves, but its his decision and we (as fans) should support his decision 100%. and...if he didn't go, he wouldn't have time for the movies he's scheduled for. He's got so many offers now. Plus, he'll spend more time with Nancy, Annie, and Johnny :)
