Sometimes I wonder whether to use "although" or "though," at a loss as to what the difference might be between them. Take this for example:<br/><br/>1. They laugh while walking down the steps as if drunk, although they are not.<br/><br/>2. They laugh while walking down the steps as if drunk, though they are not.<br/><br/>Are both of those right, one with "although" and one with "though"?<br/><br/>Thanks.
