To do anything in most situations risks some degree of offense. I wholly sympathize with parents who are dealing with loss in any of its forms. I wish there was a way they could be shielded from the world for a time. But SE Railways’ email was quite sensible.
If privacy is the concern, there’s plenty to discuss about FB or Google who actually do target people based on personal and private insights. I think that ranting about this email is misplaced at best.
