I'd like you to imagine, just for a moment, that your eyelashes grew inwards instead of outwards, so that every time you blinked, they would scrape the front of your eyeballs, damaging the corneas, so that slowly and painfully, you went blind.
Voldria que imaginéssiu per un moment que les pestanyes us creixen cap endins en comptes d'enfora, i que cada cop que pestanyegeu us rasquen la part frontal dels ulls i us fan malbé les còrnies. Lentament i amb dolor,  us aniríeu tornant cecs.
