Conjoined Twins 2: Where Does One End and The Other Begin?

What if one can swim and the other can not? Can just one of them become an astronaut? How often do they need a diaper change? If they grew 100 feet tall wouldn't that be strange? When they ride the bus to they pay one price? Have they ever been trapped underneath the ice? Are they a by-product of nuclear radiation? Have they ever been left outside a fire station? If one commits arson does the other one squeal? Have they ever been served as a rich persons meal? What if one is employable and the other can't work? Have they ever been left at the side of the road by a jerk? Will they ever be able to surf gnarly waves? Can one go to church if the other prefers home stays? Can they still find a job at the circus? Have they ever tried the stand up comedy circuit? Have they ever blown away in a tropical storm? Has a government ever weaponized them for war? Do they need a special saddle to ride a horse? Do they count as one or two at the golf course? Do they attend conjoined therapy in a group? What if one likes hot and the other cold soup? What if one gets rich while the other is poor? Could they ever have a career in parkour? Do they ever go clubbing and party till the light of day? Could they ever become president of the USA?
