Father and Mother went out to pay calls ; Miss Blake went for a ride on her bicycle , and they were left all alone till eight o'clock .<br>When they had seen their dear parents and their dear preceptress politely off the premises they got a cabbage-leaf full of raspberries from the gardener , and a Wild Tea from Ellen .
Both their parents are alive.
The text says the father and mother left to pay calls, so my statement that they are alive is definitely correct.
