I would start the sentence with "I may not always be sure..." - this is definitely true of me. Often, I am quite certainly sure of what I do not want. Used to get me in "trouble" with a past boyfriend with things like deciding where I wanted to eat, lol.
"I may sound old-fashioned, but I want to think all women should be treated like I want my wife, daughters, and granddaughters to be treated. I notice today that good manners—like standing up when a woman enters the room, helping a woman with her coat, letting her enter an elevator first, taking her arm to cross the street—are sometimes considered unnecessary or a throwback...no woman is offended by politeness." —Frank Sinatra
