I'm sorry to hear that your wife did such an insensitive thing....sometimes they seem to lack all sense of respect and sensitivity.
I don't know why they do this on these special days, I guess they are often so self-absorbed that it doens't even cross their mind.
I hope you and the children are allright, please know that there are many people here who will be here to help you and advice you if you want...take care for now, and be strong !
