Hello,<br/>I know that we can omit the subject of a sentence in informal speech.<br/> Would such exemplary sentences be correct in a note left for a friend?<br/><br/>Sorry. Am ill. Have to stay in bed and sleep a lot. Can go to the theatre some other time. Need to rest. <br/><br/>In general, do such sentences work?<br/>Had good time in Paris? (Did you have good time in Paris?)<br/>Need to go. (I need to go).<br/><br/>Thank you for your help!<br/>Kind regards.
