I despise being around people who love to hear themselves talk. I have several family members like that, and I am pretty much forced to be around them at family gatherings, during holidays and birthdays.
People who love to hear themselves talk are generally narcissists. They keep their mouth running, about...nothing. Excessive small talk. I call that verbal masturbation. I do not want to see or hear someone else masturbate. Before my FIL got dementia, he was like that. I like him much more now, because he doesn't talk much. Back in the day, I refused to get into a vehicle with him, unless I brought earplugs with me.
These days, my father's wife is like that. And my parent's daughter is like that. The former merely annoys me, but I despise the latter for many more reasons than just her verbal masturbation, as she is a meddlesome, passive/aggressive, parasitic, system-milking liberal, who was a complete failure as a single parent. Her 21 year old son does not have a driver's license, and lives in his grandmother's basement, catching rides to his job as a busboy that only pays for his video games. When she asks a question and gets an answer, she always either repeats the answer back, or says "Yeah" about 7 times. Her 7-stage laugh sounds like a laugh track from a sitcom. I cannot stand her, and refuse to call her my sister. I can't wait for this part of the year to be over, with my daughter's birthday, Thanksgiving and Christmas over with, so I won't have to listen to this crap for a while.
It's all I can do, when I am around these people, to not say, "Can you just not STFU for a few minutes"? I'm fine with meaningful conversation about real topics, but motormouths that talk about nothing drive me up the wall, and their voices are like fingernails on a chalkboard to me.
