As a very busy man, my husband is a notoriously short, blunt and to-the-point texter. So is my dad. Just no nonsense guys with no time for long drawn out convos via text. Just my two cents.
I can relate with being the only girl in my family with two older brothers. A simple minded Father..and... My fiance is the same way.*
But he DIDN'T just text a simple No. His response back was, " No, it's going to be a late day. He DID happen to explain himself. Which is what I was trying to point out. I know many simple, small details could mean nothing. But, then again if we all thought that way. No cases would be solved. Not unless it was thrown into LE's lap with a confession.
You must pick apart, and decipher what is important, and what truly means nothing. The public doesn't know much, and have little to go on. So I believe naturally it's why we pick apart what we DO know.
