DnD is a game best played among friends. Old friends if possible. When you get so familiar with your party's gaming habits that you can truly work together seamlessly, this is peak DnD. It's like playing poker. You know when they're going to fold, you know when they're going to raise you, and you sure as heck know when they're bluffing. If you can get to that level with your DnD crew, then it's like truly dissolving into another world. You don't need to stop and wait to get everybody on the same page, you were born on the same page.
Of course, DnD is also a great way to develop new friendships. There's nothing that bonds you together quicker than teaming up to fight a mythical enemy. Or unlocking secret puzzles together. It makes for fast friends. But no matter who you play with, you're gonna want to share these memes with them. It's the rules.
