I'm reading Slaughterhouse 5 by Kurt Vonnegut and I'm not sure about this fragment. Can anybody clarify this for me:
There was a still life on Billy's bedside table -- two pills, an ashtray with three lipstick-stained cigarettes in it, one cigarette still burning, and a glass of water. The water was dead. So it goes. Air was trying to get out of that dead water. Bubbles were clinging to the walls of the glass, too weak to climb out.
The cigarettes belonged to Billy's chain-smoking mother. She had sought the ladies' room, which was off the ward for WACS and WAVES, and SPARS and WAFS who had gone bananas. She would be back at any moment now.
I have no idea on what the blue text is about...
And am I guessing right that chain-smoking means smoking cigarettes one after another without any breaks?
