I listened to the dialogue below;<br/><br/>Man : Miguel’s going away party is on Sunday afternoon, right?<br/><br/>Woman : Actually, it’s not until Monday.<br/><br/>It means that actually, it's Monday. But I can't understand why the woman's reply means 'Actually, it's Monday.'<br/><br/>'not until Monday' means all except Monday; see the line<br/><br/> -&gt;-&gt;-&gt;until <br/><br/>------------l------------<br/><br/> monday<br/><br/>the negative form of until Monday is 'not until Monday'; see the line<br/><br/> -&gt;-&gt;-&gt;until ~~~~~<br/><br/>------------l------------<br/><br/> monday<br/><br/>So I guess that 'not until Monday' means the period '~~~~~'. Then the day of away party is Monday? Tuesday? Wednesday? Thursday? ... <br/><br/>I think I'm wrong. But I can't find the problem by myself.<br/><br/>Would you explain this?<br/><br/>THANKS IN ADVANCE
