ok so like vessel is your best friend that u have so many good memories with and u can tell them anything and u call them when your sad and they're just so reliable and nice and u love vessel right But regional at best is that one stranger than u meet at some bar in like the winter and u end up getting rly sad and drunk and emotional and spilling ur lifestory and all ur demons to this person and they offer some really helpful condolences and u may not speak of them much but u get some kind of closure when u think about that conversation it makes it easier to breathe knowing that its out there BUT self-titled is like ur mom or dad or some other ridiculously close ugly family member that knows all your cracks and bumps and they make u mad and upset and wanna cry a lot but they're still there for u in the end and its a nice way to let everything out and vent. I love twenty one pilots .
