One of my parents is like that, in fact it's their primary method of communicating with people. They're aware of it but never stopped, needless to say it's caused issues.
Not sure that's the reason, but I've become pretty much the opposite in many situations. At times that made people think I don't care, but I just don't think it helps to complain about things everyone already knows about.
I've landed more than once in such situations where even close people would think that if I don't complain, or don't complain enough, means I don't care or I have everything sorted out. Thing is, I rarely believe that complaining to random people moves my issue forward, so I'd keep my complaining for moments where I feel I can be helped - if only with some moral support from people capable of giving me that.
