Life is about consideration for one another. It is about selfless living and giving. It is about being happy to see another succeed, and sad if another fails, regardless of whether or not you are failing or succeeding.
Also, it is not about out-doing one another or causing untold pain to one another. We may never fathom why some people indulge in stuff that hurts others. There is nothing wrong with enjoying life, but not at the expense of another.
If you need to have a party in a neighborhood where there are clustered houses, you may need to send party invitation to neighbors who are living close to your house or apartment that maybe affected by the music that would blare from your home on the day of your party. Doing this is an indirect way of telling them, “Please, forgive me in advance for any noise this may cause.” So, on the day of the party, you will not get a knock on your door for public disturbance, which is categorized as “misdemeanor.”
Courtesy in all earnest, requires you put your neighbors in the "know" of an impending noise, so they gear-up for it; otherwise you will not be at rest. Correct?
