Delusions..

Tell me that I'm not very bright in Biology, I'll nod in acceptance;
Tell me that I'm no good in Chemistry, & I'll tip my hat in acknowledgement;
Tell me that in Physics I'll never make the grade, & I'll tell you that I couldn't agree more;
Tell me that the most ludicrous thing in the world is me trying to learn Mathematics, & I'll pat your back for pointing it out.

But dare to tell me that my English is flawed & I'll plug you in the face with a straight left.
