Sometimes friends can get into disagreements. Sometimes friends can get into arguments. But considering certain circumstances, well..
 
Sometimes friends can visit you by returning to your world through a now-open portal. Sometimes you can plan a trip along with your other friends to Manehattan to enjoy a weekend getaway in a metropolitan hub. Sometimes it can lead to a fun slumber party at your hotel involving gossiping and lingerie switching. On occasions it can lead to you and your friend to having a private conversation in the hallway about matters going on in other world. This may lead to you hearing a conversation going on in another room about a bank heist being planned. Ultimately, this chain of events could lead to you being caught for deciding to snoop and investigate when you thought they had left the hotel, which could get your magic shut down, your arms and legs bound together, and when you can’t stop arguing about who is to blame for all of this after warnings about leaving it to the proper authorities despite being the proper authority; a gag shoved into your mouth before being sped off to an unknown location before being stung up and left to ‘hang around’ until they get back, leaving you and your friend to swing and sway, only getting in the occasional death glare.
 
Sometimes, that’s something that Twilight Sparkle and Sunset Shimmer just share in their friendship.
