Dear David,
How’s everything going? I’m Li Hua. I feel terribly sorry to tell you that I broke a vase at your birthday party last Saturday and I’m writing to apologize to you for that.
Thank you for inviting me to your party. However, when I was trying to clean the spilt（打翻的） drink on the table in the kitchen, I hit a vase accidentally. It fell onto the floor and broke.
I was afraid and didn’t dare to tell you. So I cleaned the broken vase and left without saying goodbye. But I have been so guilty all these days that I couldn’t concentrate on my study.
Therefore, I sincerely hope that you can accept my apology and forgive me. Enclosed is a paper cutting made by myself.
I’m looking forward to your reply.
Yours sincerely ,
Li Ming
