Hi,<br/><br/>I got confused with a grammar note I read on a book when explaining the use of will and going to. it says:<br/><br/>decisions made at the time of speaking<br/><br/>e.g. I know ! I´ll get Dad a DVD for Christmas.<br/><br/> I know ! I´m going to get Dad a DVD for Christmas.<br/><br/>Why will and going to be used for decisions made at the time of speaking ? Is there any difference in meaning ? <br/><br/>thanks
