An example: a person is having a conversation with them about the death of an older acquaintance and will say, "she was old, 94, but she still had most of her mind intact." The yapper will absorb that thought for .4 seconds and retort with this: "that reminds me, I stepped on a tack the other day and thought I was going to have my foot amputated." Their minds are bouncing around like a frantic weasel on acid.To keep their babbling effective they also talk very loudly. The windstorm of poppycock flowing from their bionic beaks must be drilled into their cornered quarry.
These people should all be tied up, forced into swimwear and physically thrown into those 1980's isolation water tanks. Let them float in there until their chaotic internal dialogue drives them to the razor thin edge of the abyss of insanity!
Below is one of my neighbours. Every time I walk down the hallway to the elevator I hear this Yapper. Not sure if she is on the phone, has passive company or is babbling to herself. But she is loud. Chinese is being spoken most of the time.
