Diary Entry #13~ Work Experience put me off Diaries

Dear Diary, (that shouldn't be posted on the internet)
This the last entry I write with the beginning with Dear Diary. Why?
I did hospital work experience and had to do a diary of everything we did each day. When I write a diary I don't like being forced to write what I did each day. So its put me off the word diary.
How should I begin this in future.
Dear Blog,
Oh I don't know.
Farewell Dear Diary greeting. I hate you. Its a shame, we used to get on like a house on fire but alas I've given up on your greeting.
Yours forwardingly
