you walk into a room and someone is in there and starts making small talk with you. you politely smile and nod and tell them you have to get back to what you were doing as you start walking away. they say ok, but keep talking. you keep walking.
is it more rude to be the person who keeps talking when you just told them you have to get back to what you were doing? or more rude to walk away when they are still talking?
how do you handle the situation from either perspective?
