Or this.Or commission Star Swirl the Bearded to make something similar to the Equestria Girls mirror. If you can connect two entirely separate universes then connecting Ponyville and Canterlot should be trivial.Or ask Luna to teach Twilight dream magic to share dreams with her friends.Or ask Tempest about that two-way scrying crystal the Storm King used for long-distance communication.Or ask Sunset how exactly those "phones" everybody is using in the human world work, get Sci-Twi to modify them a bit, maybe build a bootleg cell-tower between Canterlot and Ponyville just to stay in touch via video-calls.Not to mention Twilight can freaking teleport directly to Ponyville, and Discord can just open portals to Canterlot.Heck, Twilight could organize regular sleepovers at Canterlot Castle and teleport her friends back to Ponyville in the morning.There are a MILLION ways Twilight could visit her friends more often. Or how her friends could visit her in Canterlot more often. Or do magical "video calls". Or whatever. IT'S A WORLD OF MAGIC, USE IT!Yes, I can buy that Twilight has a busy schedule as ruler of all Equestria.And that the "one day a month" is the sacred day where she gets the whole day off to hang out with her friends, no interruptions.But there simply is no reason whatsoever they couldn't see each other in-between, even if it's just for a half-hour lunch break or a quick chat and a hug!You could even tweak it so it doesn't contradict the final episode outright.Twilight didn't just flatout tell Luster about the Friendship Counsel right from the start; she was trying to create a teachable moment.Imagine, for a second, Luster running into Twilight unexpectedly at Sugar Cube Corner a few weeks later:__"Sometimes, friendships take a lot of work. But it's worth every second, every bit, every drop of sweat, just to spend a little more time with your friends.""Wait…" Luster blinked. "Is that why you created the international gateway system?" Her jaw fell slack. "The system that allows instant travel between seven different nations, right here in Canterlot? That sparked the greatest cross-country migration of creatures in history?""Well, it wasn't international, originally. Just between Ponyville and Canterlot Castle."__
