If you feel this is one of the least significant details of the entire story, why do you also feel the need to persistently dispute the discrepancy?
<><><>
In a nutshell:
There is a subset of freeperdom that absolutely pounces on any discrepancies in reporting, and uses those discrepancies to turn the entire situation into a major conspiracy, involving the government and the MSM. You pointed out such a discrepancy (22 months old or 3 years). Added to that was your concern about mom skipping work to be with her hubbie and did she know her child was ill. Which is also apropo of nothing. But exactly the kind of thing conspiracy types love and run with.
Go back and look at Newtown and the Boston Marathon bombing threads here on FR. You should very quickly see what I mean.
If I mistook you as one of them, my apologies.
I have no desire to read those old threads. I am not a conspiracy theorist. I am interested in facts and how they may affect the outcome of the trial (ie: who are believable witnesses). I don't see either side of this tragedy as a saint or a martyr. I see one as a grumpy senior citizen, and one as a self-absorbed texterrific media addict.
I will accept your offer of apology for conspiring to believe I am a conspiracy nut.
