I would have been weirded out also, but that being said I agree with the possible Alzheimers and/or lonely person. Sometimes people are so lonely they try to start up conversations and are not really "trained" in how to do this. I have had that happen to me quite a bit. I tend to draw "wierd" people. Maybe becasu I am a geriatric mental health nurse. I usually talk with them if they are not too weird.
