Feeling naked without my seat belt

On the way into my apartment complex this evening, I stopped to pay rent. So I had to get out of the car. From the office, I have to drive down a hill, around a turn and then park in front of my building. I decided that I did not need to wear my seat belt for this. But I felt naked the whole time. It just doesn't feel right when I don't buckle it right away. When I lived in Georgia, the driveway was really long and the mailbox was at the road. So, I would pull up to the mailbox to get the mail before driving down the driveway. But, being short, I also would have to unbuckle my seat belt to get the mail. 99.4% of the time, I would buckle my seat belt to drive down the driveway. It just felt better that way. Am I crazy, or do others feel that way too?
