I remember this story from a few years ago. I love it.
Fucking poor people: don't buy high rise condos that don't have privacy glass. I bet they don't even have SubZero appliances. Ugh, disgusting.
Totally serious question: if you have sex on the couch in a place like this, obviously children could see from the platform. Could you get in legal trouble (something like the UK equivalent of Indecent Exposure or something)?
Not totally sure about the UK, but in the US, the answer is
mostly no. If you're really egregious and obviously trying to get attention and expose children to obscenity, someone will hold you accountable in some way, but in terms of typical things like public indecency, exposure, etc., no, you're usually protected inside your own home especially from other non-public spaces. Laws vary from state to state, but in most places, you'd be protected.
But if you're overtly trying to offend people in public with lude acts in private, then you'll probably be held accountable for something, eventually. Like, if your house is across from a school or park and you install large picture windows and stand there with your dong out with the clear intention of goading children into looking at it, then... yeah, someone will find a law that you're clearly breaking.
