Change?

1st Practical class for Database.
The lecturer is an ass.
Scolded me and my friends for wearing slipper to the class.
Well, we know slipper aren't allowed in college,
But even the security guards doesn't stop us from entering college.
What's your right to scold us then?
Your brain are too stubborn as well to accept answers from student.
"Your answer is not impossible, but it is very inefficient"
What do you expect from me?
A perfect answer?
I would be glad if you just tell the goddamn answer instead of keep repeating the "impossible and inefficient" stuff on me.
Seriously, your 1st impression for me,
I don't like you much.

A friend been telling me to change and improve a little part of me on how I treat girls.
I don't know what I should change.
Becca told me that maybe I treat girls too good.
She said I need to be bad ass a bit because girls like it.
Ahhh, I don't know what happen to me.
I think I should learn how to know when a girl feel that you are annoying.
I'm seriously sucks at that.
