Sometimes, the simplest unfinished sentences I wrote elicited the widest range of responses.  Here's one such sentence and its responses from the early '90s:
On second thought,...
...who is going to wash the dishes? (Michelle T.)
 
...I guess I am the master of my universe, and I am in control of the choices I make, thus being responsible for the consequences. (David R.)
...why should you match pairs of socks--when they'll eventually become "lone socks?"  Uh, never mind... (Roberta M.)
...let's not have people over.  It may scare the dog. (Doug D.)
