Something I haven't noticed before:<br/><br/>is it true that when the name of a day of the week is preceeded by<br/><br/>next or last you DON'T use the preposition ON?<br/><br/>So, for ex.:<br/><br/>I'm leaving on Thursday<br/><br/>but<br/><br/>I'm leaving next Thursday.<br/><br/>Is it correct?<br/><br/>Thank you
