Is it appropriate to say, "Bob was not sure whether Kate was at work. She might be at work."?
In my opinion, "Bob thought, 'She may/might be at work.'"is correct.
Switching it to indirect speech, "Bob thought she might be at work." is correct.
So, omitting "Bob thought" without misunderstanding, "She might be at work." is correct.
However, there is another saying that there's no simple past form of "might". We must use "might have been" to refer the the past time.
Could anyone help me out with this problem? Thanks a lot.
