No...you say excuse me when people are around so they can excuse আপনি for your bad manners. When আপনি are alone, burp your গাধা of cause no one is there to be disgusted দ্বারা your disgustingness :3
When people are around then yes... but when I'm alone I never use my mannners. But when its near the end of the বছর and I'm sitting near the বড়দিন বৃক্ষ then yes cause I wanna get stuff from santa... XXD
