I realized what bugged me so much about the below comment. It is not so much a question of "Why would someone say something so insensitive" as it is "Why wouldn't someone say something so insensitive???"
The thing is, we don't talk about death in our society. We don't teach our children what is acceptable and appropriate to say to someone who is grieving the loss of a child/parent/spouse. And that is what frustrates me. How would the quoted person below know that he/she is saying something hurtful? Heck, I might have said the same thing in my previous life.
I think, however, that what not to say is a little more intuitive with other losses. I might be wrong here (feel free to correct me!!). But I would hope that it is obvious NOT to say to a widow "Gee, I am so glad that my husband of 15 years is still with me. Seeing your struggles as a widow make me cherish my husband even more."
I just don't know. Might I have said this, before? Might I mess up and say something equally dumb in the future? I suppose I might. We are none of us perfect.
But we spend so much time teaching our children proper socialization in so many other ways. This is such a missing link.
