Is it abnormal to feel uncomfortable when people around me slurp their food or chew without closing their mout? - mout & blade

My parents eat well and I always crawl when I hear it sucked or chewed. I was told that this will eat the way people feel and I have to get used to it. But it's been 20 years and still not used to it. I like it at the same table with my parents, because to eat it.
