but you know - 'smart' doesn't mean some straight-A-student. A person can be a brilliant mathematician, but use awful grammar. and still be a genius.
and then there's wisdom of life - my gran is no scientist or an intellectual, but i think her rather smart and always ask her advice.
and it's not who you are, that defines whether you're smart or not.. it's what you do! judging others doesn't make you smart - it makes you pompous and pathetic.
