Have you had time to think?
Do you think out loud?
Have you put your thinking cap on?
Are you thinking outside the box?
Have you thought ahead?
Have you stopped to think?
Are you thinking alike?
Is it wishful thinking?
Are you thinking big?
Did you think nothing of it?
Can you think on your feet?
Is it sooner than you think?
Are you thinking positively?
Are you having second thoughts?
Do you think highly of someone?
Can you hear yourself think?
Have you thought it through?
Are you doing all the thinking?
Do you want to think it over?
What do you think about your thinking?
