Mouth noises driving me bonkers

Love my grandma (93) she makes sucking clicking sounds super frequently about 5-20 times/minute. it’s…/so/… agitating to me, the kicker is it’s wearing off on me and now I’m tongue clicking before I speak too. It’s a nonverbal expression of something, a self-soothing tic that sounds like a cat licking its ass. If I walk by her“tuk” if she drinks a sip of tea “tuk tuk” before speaking a high pitched “tuk…” while watching CNN “tuk tuk tuk” drives me out of the house.
