Ask Pointed, Uncomfortable Questions
No matter how curious you might be about whether or not your cousin's children are a result of a sperm donor or how concerned you are that it looks like your niece has lost -- or gained -- weight since you last saw her, remember this: Family members tend to lack consideration for each other because they're so, well, familial. We no longer consider each other's feelings, and we overstep or ignore the boundaries of our relationships.
Experts recommend we try not to take such questions as personal attacks, and that most of the time this sort of inquiry into your personal life (or secrets) is more an act of concern than anything malicious. Remember that when you find yourself cornered by your aunt who wants to know when you are going to get a better job, get married, and get started on that family of your own.
