Person A to Lectuerer who just gave a lecture:<br/>Don't take the walk-outs personally.<br/>The lecturer said:<br/>I hadn't noticed.<br/><br/>Why is "hadn't" used here? is it some kind of condition, like:<br/>I hadn't noticed if (until) you told me?<br/><br/>Correct me if I am wrong.<br/><br/>thanks,<br/><br/>Ench.
