Maybe you feel you can trust everyone in your family, but this is far from universal. Many, _many_ people have family members who are self-entitled moochers who think that everything bad that has happened to them was because of other people instead of a lifetime of own poor choices. When they find out that someone close to them has come into some money, they feel (and act) like they "deserve" some of it and will try all manner of tactics to get at it, including pity and made-up stories, all the way up to blackmail, threats, and physical violence. In a word: toxic. Sometimes it's just one family member, sometimes it's the whole family.

If you have none in your family, consider yourself extremely blessed. Most of us are not so lucky.
