Dear M:
I'm terribly sorry that I cannot attend your birthday party.I failed in my last exam, therefore I must study hard to meet the important exam this time or I'll be blamed for. Moreover, I've known that you always want to receive a wallet in your birthday by some ways.To express my regret,I chose a lovely one with a Snoopy on it as a gift for you.I hope you'll like it.
Please forgive me for my absence,again.
Hearty birthday congratulations to you!
Yours
Li Hua
我非常抱歉我不能参加你的生日聚会了。我上次考试考砸了，所以我必须得认真应对这次的考试，否则我将会被严厉责备。另外，我从别处得知你一直想要在生日那天收到一个钱包。所以，为了表达我的歉意，我选了一个上面有一个史努比图案的可爱钱包作为礼物给你。希望你能喜欢。请再一次原谅我的缺席！
衷心祝贺你生日快乐！
