Thanks for the good vibes and responses, folks.
I’ve lived in communal settings all my life - four of us at home, living in duplexes all of our lives until HS; college, living in dorms, and being an RA; after college, teaching and living with roommates in a house and then an apartment complex; grad school, apartments. So I have a pretty high tolerance for the normal types of noise (feet upstairs, occasional loud voices, even loud music at times). But these guys… they are the stereotypical 20-something tearaways. They like cars and beers (and presumably women, though I rarely see them around). So everything they do is centered around this.
As my OP stated, I have no problem complaining. I just don’t like doing it. And in apartment living, one must balance complaints judiciously. Unless the people are on the road to eviction, they’re not going anywhere, and it doesn’t help to have enemies upstairs/next door.
My new neighborhood in Austin has a HOA, which my dad warns me about, but they have rules like “No loud parties after certain hours,” and “no cars parked on the street overnight.” My mom heard this and asked if there was a parking lot nearby. To which I replied, “In what circumstance can you imagine six people with cars overnight at my house?” (My parents and in-laws live in Austin as well.) They also have rules about picking one’ garbage can up after the dump truck comes by. Here, on the other hand, my neighbors do not secure their trashcan (I bought a $5 chain at Home Depot and wrapped it around the standpipe), and if it’s windy, I can usually find their can rolling around in the street.
As I said, I rarely see their trashcan out on trash day. So I suspect they accumulate trash over a period of months, then they take down about four 33 gallon bags of refuse. I already mentioned the mountain of bottles that are for recycling. There are enough cars that they could drive down to the supermarket and return them for deposits, and make enough for a few free six packs! (Hey, I might do that, but I don’t want that nasty shit in my car.)
I’m pretty sure the neighborhood I’m moving to would be unappealing to the fools upstairs. It’s family oriented. It’s quiet. You have to join a HOA. It’s in a residential area, so no bars/clubs/liquor stores nearby. I can’t wait to go out on MY porch, without seeing somebody’s shit on it, open a beer, and just chill. Maybe work or read out there, knowing that nobody’s touched my smoker.
I guess I have a weird reverence for people’s space and personal property. I won’t even let my friends who visit park in their driveway - they either park in mine (I move my car) or I direct them where to part. If my washing machine’s broken, I’ll fix it rather than bum a wash off their machine. It’s the principle, I guess!
