I'm watching a basketball game on TV with a friend of mine at my place. When the first half ends my friend says he'd better be going. I want him to stay so I ask:
Are you sure you don't want to stay for the second half? (1) / Are you sure you don't want to stay and watch the second half? (2)
Does the first sentence mean the exact same as the second? Would the first sentence even be more natural than the second?
