What could you do on Titanic if you were third class?

Hang in rooms or diners, and be on deck when 1st and 2nd class is not around. Being ordered around by loud stewards. If you're a man, you share a cabin with some men who don't speak english. Mothers usually share theirs with their children and I don't know where the babies sleep in 3rd class. If the ship was sinking and if you were an immigrant it would be impossible [if you were a woman or child] to get into the lifeboat.
