You know, I think that professions determine our attitude to cellphones. Some people don’t answer cellphones if they have clients. It might very well mean, they don’t answer the phone all day, till the late evening.
KB is a flight instructor. Meaning she either may not get a call in time, or not answer it if she is busy. It might apply to her relatives or close people as well. Or perhaps she does not like taking calls?
Shanann Watts was the opposite, and it helped the case immensely. She was a vendor, in touch with her clients and her group. She would take every call, because a call might mean, sales. She was also super organized and “on the clock”. Small wonder her not answering the calls on the morning of August 13th was so much out of character that her friend immediately called the police!
Not every person is as organized as SW. Most are not in sales. I think it might well be been KB’s style to not always answer the phone. (Busy or out of reach at work, tired single young mom at home). I think that sadly, this was the reason no one had noticed her absence until a week went by.
