You made PERFECT sense. I'm the same kind of mom. Since my two, now adult children were born, I've always said I love you before they went to bed, to school, to go outside and play....even now, they can send me the most benign text message and i'll respond and then add I luv u. I'm almost (if you asked them) obnoxious about saying it....but, trained them well, cause they in turn feel compelled to tell me I love you all time too.
My point was, that for some reason, it disturbs me that Somer's mom-what's her name?-felt compelled to share with the world that she couldn't remember if she said "i love you" to Somer Monday morning or not. Almost sounds like a guilty concious to me. My feelings about this woman are just that. eerie uncomfortable feelings. No basis in fact, other than there is no denying the woman can sob and wail Very Loudly without producing tears........and she really seems to like attention and cameras.........
I would imagine she does feel guilty, I have felt guilty when something happens thinking I could have, would have, should have.... Although we cannot control some things I think as a parent we feel guilty over things we cannot control and should not feel guilty about.
On the tears thing, I think people act strange period when confronted with an unexpected death. IMO it takes quite some time to adjust to the fact that a person is dead and behave in a more normal way.
On the uncomfortable feelings I totally understand, gut feelings.
