Sometimes it doesn't necessarily mean relatives, it can also mean neighbors, especially those who come to your house and tell you what to do. In fact, I personally, distant relatives seldom ask more private questions, more intimate relatives are not the kind of big mouth, their questions are really concerned. But when someone does ask questions that they don't really want to answer, they can choose to smile awkwardly or give a perfunctory answer, and are generally more understanding.
The first thing that comes to mind when discussing this is childhood. You may be difficult to appreciate the kind of when your parents are scolding you is that aunt in the side of the help of the kind of stifling. Nay there was no power to fight back at all, you couldn't even talk back or mom and dad might hit even harder. I was refusing to eat the Lord, but also the mouth often hit the nail on the head, mom hit the whip is also blood. Most of the rural areas believe that the stick out of filial son. In fact, it does not exist, I only believe in the role of the parents' model.
At adulthood, the aunts will generally show due respect, the subject of discussion from the embarrassing into a variety of life issues, the saying is called "which pot not mention open which pot". Whether or not they failed college, the worries of single dogs, the unaffordability of a house and car, high or low wages, whether or not the job is going well, there is nothing in life that escapes their attention - the problems they encountered in years gone by. It's hard to pinpoint what kind of mentality it is that makes them think to embarrass us with these problems, or maybe it's the fact that they see other people's lives going badly that makes them feel more confident about their own? The response is simple: fight fire with fire, and rhetorical questions are indeed a good answer. But I guess if one runs one's own life well, wouldn't one be able to force-fit* through the mouth of one's aunt?
So whether they are annoying or not depends on the state of your life, every family has a difficult time, try to understand each other
