The story of Cowslip

They started with three young heifers. Then

Several years later Snowdrop suddenly died. Cowslip stood next to Snowdrop's dead body refusing to leave until Snowdrop was buried. It was after Snowdrop died that we realized there was something very wrong with Cowslip. Our neighbor took one look at her and said she was blind. Then it all made sense. Snowdrop had been her eyes and without her old friend she was lost and afraid of the other cows and new places. Judging by Cowslips pale brown eyes, I'd say she been born blind."
