I am sinful

Dear buddha,

I am sinful.
I made a mistake today.
I forgot to go for my art teaching lesson today.
I FORGOT ABOUT IT. TOTALLY.

Until my student's mum called me...
and I said "SHIT! I TOTALLY FORGOT!"
I was too honest.

My reply was worse than not going for the lesson.

And so...I guess she must be angry.
I feel really bad.

Once again,
I am so sorry.
I AM SO VERY SORRY.
I REALLY AM.

PLEASE FORGIVE ME.
