They think it is strange that you don't run with them into the same excess of riot, blaspheming:

 Peter's mind is dominated in this section by the conviction that the end of all things is near. It is of the greatest interest and significance to note that he does not use that conviction to urge men to withdraw from the world and to enter on a kind of private campaign to save their own souls; he uses it to urge them to go into the world and serve their fellow-men. As Peter sees it, a man will be happy if the end finds him, not living as a hermit, but out in the world serving his fellow-men.
