You bet I observe Christmas because otherwise its quantum state is indeterminate. Do you want a Santa who is both dead and alive??
@jef he is fallen! (from the womb)
@jef Are Santa and his cat entangled?
@jef
Santa's position is also indeterminate until he is observed and can deliver the gifts.
@jef I opened a possible gift once. I don't recommend it.
@jef Santa only live during Christmas season I'm for sure
