Death is something that is hard to take, but death can be harder when it comes to losing a parent. When you discover that someone has lost a parent, offer your condolences and offer your love and support. In case the person affected does not care that their parent has passed away, try and figure out what their relationship was and talk to them on how they might have wanted things to have been. But if they do not care, do not push them.
