I spent years playing an MMORPG called "Maplestory" where me and my online friends would just sit on virtual chairs and talk to each other.

There was something called the "Free Market" where there were no monsters to kill (so you couldn't die.) Guilds claimed different Free Market rooms as their "guild rooms" and people would just go AFK there. You'd always be able to find friends hanging out and talking in these rooms.

You could spend real-life money on their cash shop, which had cosmetics and small things like virtual chairs or couches to sit on.

You could even buy "friendship rings" that would display animations if the two of you were in close together.
