hello,<br/><br/>WHen you use "on the other hand," do you always need to have 'on the one hand' before it?<br/><br/>For example.<br/><br/>I can go home. On the other hand, I can go to the bar.<br/>On the one hand, I can go home. On the other hand, I can go to the bar.<br/><br/>I don't think "on the one hand" is necessary. BUt can you tell me the correct answer?<br/><br/>Thanks.
