When writing in the past tense, consider two sentences:<br/><br/>He wanted a break because the <b>last</b> three months had been hectic.<br/><br/>or <br/><br/>He wanted a break because the <b>previous</b> three months had been hectic.<br/><br/>Which one is correct? Must we avoid <b>last and stick to previous</b> when writing in past tense?<br/><br/>Thanks,<br/>John
