Exactly!
I'll add:
Be forgiving of others. Allow that others have different ideas of "camping" and don't jump on them for everything you don't like at the very first instance.
And if you are having an "event" that will include music, loud cheering, etc, or have kids or a young dog that might be annoying to others, be proactive. Let your neighbors know that your baby has an ear infection and might cry during the night, or that your new puppy is still learning his camping ettiquete, and so on, and your neighbors will be a lot more understanding.
I once had a stag party in the site next to mine. When the 8 or so 20-something guys showed up, they came over and let me know it was a stag "campout". They told me they didn't want any trouble and if they got too loud to just tell them to shut the f up. They were great campsite neighbors. They had a blast and I didn't stress that if it got too loud (it didn't), I would be dealing with jerks.
