Dear Mrs/Mr：
Peter, I would like to know if I could ask for a casual leave of absence for one day on April 4th, this Wednesday.
This morning I received a telephone call from my dentist, urging me to come to his practice for immediate treatment of my teeth. I have been experiencing a stinging pain, depriving me of my sleep during the past fortnight. The situation could worsen, should infection occur.
Concerning my workload: As Wednesday is not as busy as the other weekdays, I think a one-day leave this Wednesday may be the best solution. I apologize for the inconvenience my absence from work may cause.
Thanks. I will call you at 1:30p.m. or you can call me at any time.
