That's not just Berlin, my dear. Here in mid-Michigan, we have a woman that stands outside the local grocery store and asks everyone walking by if they have seen her husband. If someone stops, she breaks down crying and tells them how her husband left her, 20 years ago and she is still waiting for him. Then she laughs and starts asking about her husband again. She never asks for money or food, and is harmless if no one stops. Every couple of months, she gets taken away for a few weeks while they change her meds, but she always comes back.
Oh! I guess every community has their share of eccentric people! And we'd miss them if they weren't there...!
