My family is a bunch of weirdos and I don’t know where to go from here.

I’m 15 and I’m about to go to a family dinner. We live in a house that is 4000 sq. ft. We have a basement and we have a garage and we have a room in the basement with a shower in it and some kind of room setup. My uncle (let’s call him Sam) lives in that room in the basement. It’s been this way for over a year. It was like when Sam first moved in he would just be in the house with us but now he just stays in that room in the basement all the time and comes out like once every 2 weeks. I don’t know if he has a job or what he does with himself in there. My parents don’t ask questions about it and I don’t know what to do. <br><br>My family is weird. I don’t know how to explain it so I’ll give you an example. My dad has this weird thing where he thinks that every time he sees a car go past our house he has to pull out and wave at the driver. It’s not a joke or anything. He’s actually serious about it. Everytime he sees a car go by he pulls out of the driveway and waves at the driver. It’s really creepy. I have seen him do it like 15 times a day.<br><br>We also have a tradition in my family. We always have to ask each other if we can use the restroom. If we’re in the bathroom we always say “can I use the restroom” and if someone is in the restroom they say “no”. That’s how we communicate with each other in the house. But it doesn’t stop there. If we can’t use the restroom we have to go outside to the garage and open up the car door and ask to use the restroom. If someone is in the car and doesn’t say “no” we can use the restroom. <br><br>My uncle has this weird thing where he only eats certain foods. My mom doesn’t ask questions about it and lets him do what he wants. He only eats like 5 foods. He eats like 5 cans of black beans every day. He eats a lot of bread and he has a big jar of honey that he keeps in his room in the basement and eats all the time. My mom makes him his own food and she brings it down to his room in the basement and leaves it there for him. <br><br>We all have our own rooms and we all share the bathroom and the rest of the house together. We are all very weird and we don’t get along very well. I live in a constant fear of being yelled at or being yelled at for no reason. I live in fear of going to my room in my bedroom and finding my uncle in my bed. This has happened before and it scared the shit out of me. <br><br>I don’t know where to go from here. I’m about to go to family dinner.
