I hear you. No fun. I have extremely difficult father. My mother wasn’t difficult, she was an Enabler, but she passed away.
Mine lives near by and is a hoarder and I am currently cleaning out his house because it became a hazard. He’s getting old but is still extremely sharp mentally.
Few years back, I think I was about your age, my parents had to stay in my house for 3-4 months because they were between houses and had no place to stay, complicated situation. It was a nightmare. At some point my daughter, little at the time, asked “mom when are they moving out so it can be quiet again?” Lol
Try to focus on the ocean, being outside and staying on neutral topics so you can survive 6 days.
