It would be awfully presumptuous and disrespectful of me
To assume
That I know and understand everything
(For even if I studied one thing for my entire life
I still wouldn't even come close
To knowing everything about that thing)
Or that I could fully understand you
(You and I
Are two different beings
With two very different viewpoints
And for me to assume
That I could see as you do
Would be quite ignorant)

However

It is equally presumptuous and disrespectful of you
To assume
That I am incapable of understanding and knowing
(In fact, I already know quite a bit:
I've been studying up
And though I'm still a beginner
And there are some things I don't quite get yet
I still understand a lot)
Or that you know everything about me
(Again, you and I
Are two different people
And I see things that you don't see
And for you to insist that you can read my mind
Would be the very definition of patronizing)
