Caller type: Unknown
The person calling asked if "John" was there, and I replied "Absolutely not". I have gotten occasional calls of this nature, not knowing if the caller is referring to my deceased FATHER John or my moved-out-40-years-ago BROTHER John. I don't even know how people who are obviously out to scam me or my widowed mother, get our number in the first place.
