OMG, yes I've always had a problem with this one, I think EVERYONE does. And I've heard of people reminding widows or widowers that "You won't be able to marry your spouse again". I swear, if I EVER heard someone say that in earshot I would take them and rip them a new one, I don't care WHO said it. There are some things you just don't say if you have one lick of decency or compassion.
And yes, it does strike me as creepy, always has.
