Sometimes I wonder how someone can be so stupid or annoying without even knowing that they are.
For example, in my neighbourhood lives an old woman. Every year she sends me a birthday card and some money, which I always personally thank her for. I'll walk up to her house, ring the doorbell, but before I can say anything, she opens the door and starts rambling on and on about literally anything...
Last time she told be about her childhood, how she met her husband, what jobs...
