Dear Man, how lovely it is to realize that etiquette and courtesy are nothing more than relics of a distant past. After all, why go to the trouble of ASKING for permission to share your audio when you can simply impose your sonic presence? This behavior is as pleasant as diving in the Arctic! Please do not feel embarrassed if you have done or are in the habit of doing such a feat. It is a privilege to serve as an involuntary audience for your vocal performance.
