A New Excuse for Language Incompetence

My Chinese teacher today asked me to answer some questions in Chinese characters today up on the blackboard.  Well, my characters are VERY limited.  So I told her I couldn’t and she shook her head and said “oh ya, you are fat and tired, you cannot go do the work.”  I shook my head “yes, yes that is it.”  It has nothing to do with the fact that you’re writing in an impossible language, it’s just that I’m fat and tired.  I’m gonna use that excuse all the time now!
