Which type of housing suits me? Probably not a house...

that has good entertainment value for a Sunday. or pianist your problem is definitely not a house in a supposedly unattractive location. Most people separate from their parents at some point (about 20 years earlier than you), that should also be your next step. And yes, you can do that even if the parents live next door. Regards Guitar, uh.. flute

And how exactly am I supposed to do that? The other day my mother said to me in a very serious tone: "Something is bothering me. I happened to see you leave the house yesterday at 10 PM. Should I be worried about that? I couldn't sleep all night." The fact was that I forgot dinner because of all the work and then walked to the kebab shop.

Where she is right, she is right. At 10 p.m. a döner is hard to digest.

What is it like, for example, to live on a boat?

Living on a boat, if it is comfortable, I find great. I had considered it for myself and my husband as well, but it failed for various reasons. It definitely seems interesting and not mainstream.

Is one considered innovative there? Or does one create the image of a sociophobic oddball?

In my estimation, that could fit well in Berlin without you being perceived as sociophobic or odd for this reason. It is original in a positive sense and fits, beware of prejudice, somehow with Berlin.

I just have to make sure that I can continue to practice my profession there; so far my recording studio is in my basement...

That could be a viable compromise for you and your parents. You work as before in your basement but live somewhere else. For most people, workplace and home are separate. Whether that is easy to manage in your profession, I do not know. Perhaps your boat can be big enough that you can also work there if the technical conditions are met.

That sounds extremely ideological. Maybe consider whether it is the right approach. I would also initially have a problem if my future partner voted Green or Left, but that is no exclusion. Likewise, if she were religious, I could come to terms with it. A person is much more than that. Just a tip.

I would also be reluctant to date Nazis. Belief, love of the environment, and the dream of a more solidaristic, humane world is something different than adhering to a dehumanizing ideology in whose name millions were murdered.

Is the post really to be taken seriously? I have doubts. If I am wrong about the OP, I am sorry, but something is definitely not right here with an adult man.
