Just a short anecdote. I occasionally give my friend, Ruby, a ride home. As I drive, we normally chat, laugh and giggle. Sometimes, as is my wont while chatting and driving, I do some things without being aware of what I'm doing. Several times, I have found myself making a left turn when what I really wanted to do was continue forward. I say "Ruby, why didn't you warn me I was doing this?" Sixties hippy that she is, she says, "Heaven forbid that I should be the one to curb your leftist leanings!"
