- If she were a time traveler with a cell phone, who could she be talking to? A cell phone network did not exist in 1928.
- Perhaps it is not a cell phone, but another kind of communication device with which she is talking to another time traveler, perhaps.
The time traveler explanation is pretty far out there. Logical explanations include:
- She is using a Lutz Ferrando ear trumpet, a kind of a hearing aid. But it was used for hearing only, not talking, and the woman in the footage is doing a lot of talking.
- She is a lunatic talking away into a box of matches or something.
