A little bit loud, a little bit rude.
When me and one of my friends are in public, she always makes comments on the people around us in a voice that is so loud that the person that she is talking about can hear. It's not like she always says bad things, but it must be awkward for the person on the receiving end of one of her comments, and it's awkward for me because the person always turns to stare (or glare) at us. The weird thing is that my friend always thinks that she's whispering, but she's actually making a clearly audible comment. Do other people do that too?
