hello~<br/><br/>I wonder if there is any difference in nuance between '<i>hard</i>' and '<i>difficult</i>'.<br/><br/>For example, <br/><br/>"He asked me a difficult question." vs "He asked me a hard question."<br/><br/>Is there any difference in meaning and nuance?<br/><br/>Would you please explain it? : )<br/><br/>Thank you in advance~!
