Can Congress work on 2 things at once?

Before watching some of the Sunday news shows, I was taken aback by the fact that everyone says that nothing can get done in Congress until the budget resolution gets done in March. After all, with all the committees both in the House and the Senate, can't more than one thing work its way to a vote? And then I watched the shows and realized, of course Congress can't do more than one thing at a time. As a matter of fact, Congress normally can't even do one thing at a time. Why? Because normally, Congress isn't in session. As a matter of fact, neither the House nor the Senate will be in session this week. So, we elect officials in November, they get sworn in on the first Thursday in January, and after a very tough Friday (1 vote on hurricane relief, which was tough, I'm sure), they have at least 10 days off? No wonder Congress can't do two things at once. They're barely in session long enough to do one thing.
