Letters to the headteacher: tired and emotional

Dear Headteacher,

I am writing to you to request a couple of days off for the important purposes of rest and relaxation. I have recently spent several long days teaching and as a result I am feeling both tired and emotional. I am convinced that the only effective solution to this is a couple of days spent horizontal on the sofa in the company of a couple of large bottles of wine, and possibly some crisps.

I am sure that you will appreciate my urgent need, and look forward to your swift response.

Yours sincerely,

Ms V. Sandwiches.
