Viewing life through the lens of your own pain is an unhealthy way to live. As is begrudging other people's happiness. Couples are allowed to announce a pregnancy when they feel it is right, not when strangers deem it appropriate. Someone would have always found fault with the timing. The daily fail would have made sure of it.
White Cane Safety Day, isn't about unsafe white canes, it's about celebrating the achievements of blind people. My point about other events on this day was in support of what the OP said by giving examples.
"Yeah I don't think it was purposely hurtful - without meaning to sound insensitive there's always a "National X Day", and I'm sure the women and men that have lost children will be equally hurt any other day"
As an aside I've often marvelled at how something as simple as washing ones hands has saved many lives. Doctors and nurses use to just wipe their blood soaked hands on a rag then move on to the next person or if they were lucky a quick dip in a bowl of water that they'd already used for the same thing earlier.
