The Texas Rules of Civil Procedure

You are being deposed in a case filed in Texas under the Texas Rules of Civil Procedure. The last question ended and the sixth hour of deposition time just passed. The attorney, asking you questions, just asked you if you are ready for more questions and tells you that she has about an hour of questions left. Should you get up and leave, stay for the next hour of questions, or what?

Now, what if the case is filed in federal court under the federal rules, how would your answer change, if at all?
