Question

1. The dog sits under my desk.
2. The dog is sitting under my desk.

(What is the difference between Sentence 1 and Sentence 2? What is happening in #1? Is the dog under the desk now or not? I think in Sentences 2, the dog is under my desk. What about in Sentence 1?)

Answer 1

The dog is currently sitting under the desk in 2, and 1 only indicates that he has the habit of doing so, although it could be happening currently.
