Read this excerpt from the people could fly.

i have children and grandchildren now. well, you know, the bigger ones don't care so much to hear about those times. but the little ones, well, they never get tired of hearin how their grandpa brought emancipation to loads of slaves he could touch and feel in the dark but never ever see.

how does the speaker feel about his role in the underground railroad now that he is older?

he wishes that he had never put his family in so much danger.
he wishes he had done more to others when he had the chance.
he feels proud that he so many people gain their freedom.
he feels grateful that he was able to get back at the slaveholders.
