Is it cultural or personality?

I find myself frustrated at times because of this confusion. I constantly have to sort out if this person’s advice is true to the culture I find myself in or if it is their interpretation of the culture because of their own personality and preferences. I’m sure I’m driving the other white people crazy here. Some of the advice that I receive I take it like I would take advice from anyone that I just met, with a grain of salt. I have to weigh everything I hear. This has gotten very old after a month.
