Back to an old thread: what's the impact of adding a new children to a set of children? -- whose answer depends on the cardinality of the initial set.
Hmmm.... IIRC, I read somewhere [and probably more than 20 years ago] that the human mind does not understand instinctively any number above 2. I think I agree. Getting out with two children, you *always* know where they are. You keep a constant track of them. With three or more [today there were four - niece included] our inconscious mind *always* sends messages requiring us to *count* them, in order to verify if they are all near. Alberto Monteiro
