Vash wakes up somewhere around dawn to a gorilla knocking at his window. He politely thanks the gorilla and tells him that he'll go to breakfast as soon as he finishes his morning routine. He and the gorilla have An Understanding.
Vash spends exactly three seconds reaching a zen state on life, the universe and everything. And love and peace. Then he spends the next two too three hours working out. This includes finger pushups (VASH HAS YOUR NUMBER, SHIN), pullups, sit ups, and balancing fragile objects on the tip of his gun while doing flips with his eyes closed and various other weird gun ninja shit.
Then he takes a shower and goes to breakfast.
Feel free to assume you talk to Vash at breakfast. He's very socialable and probably is talking to SOMEONE most mornings. He eats whatever is being served and thanks the chefs every time and spends the next hour or so eating and making a fool out of himself.
Vash then spends the next several hours until lunch wandering around, talking to people and helping with whatever he can. IF YOU EVER WANT TO ASSUME THAT YOU'VE ALREADY MET VASH, BY ALL MEANS, just ping me so I know. Cause like. Wandering around helping people makes up about 90% of his free time.
Vash does not restrict his socializing to the living! He's been known to dine with zombines and lunch with gorillas and yes, he's met Marcy. They're on good terms.
Vash also wanders around SNOOPING. I.E. He was recently lost in the labs for a week where he located a PLANT. Snooping usually results in Vash running for his life.
Vash visits the church. He also LIVES in it but it's not the same. He will stop by once a day to once every other day, and stay there for anything ranging from a few minutes to about an hour. If you can't find Vash well... okay no he's probably NO in the church he's probably running around the Caves of Despair screaming like a girl. But if you can't find him THERE he's probably in the labs and if you can't find him THERE he's probably in the church. Vash in the Church is Busy. Emoing. Do not Disturb.
Vash keeps up with posts! He doesn't read comments a whole lot, but he reads most posts in a general effort to keep up with what's going wrong, and in the event that someone need help he can lend to them? He's there (ONLY NOT REALLY CAUSE I HAVEN'T BEEN THAT ACTIVE. He's there in spirit).
He will probably look in on Gwendal and/or Wolfood at least once a day to make sure they're alive and not killing each other/breaking up.
And otherwise he basically screws around until nightfall, at which point he repeats all of his morning exercises again, takes a shower again, and tends to any new wounds he got during the day. Then he gets in his PJs and goes to bed!
