I am somewhat a stubborn person. stubborn and illogical. I guess a lot of us are like that. We may know what we ought to do, and even know the consequences of doing (or not doing) something that we ought.
Even more so when you are about/or will be doing something that is expected of u but someone reminds you to do so (in a short, well, imo, short span of time). My brain will translate it from a perhaps intended “gentle” reminder, to a “nag”
I guess it feels as if the person doesn’t trust you. ESP when that person is someone who’s close to you. For that moment, you feel as if that person is not close to you just becoz the trust seemed to be gone for that moment.
