A: Don't bother buying me a present. I hate birthdays.
不用费心帮我买礼物了。我讨厌生日。
B: Too late. I already bought you one.
来不及了。我已经帮你买了。
【don't bother 别费事，不劳】
don't bother后面可以接四种不同的结构：
1. -ing: Don't bother coming back.
2. 不定词:Don't bother to come back.
3. yourself + -ing: Don't bother yourself coming back.
4. yorself + 不定词:Don't bother yourself to come back.
以上四句都正确，但以(1)及(2)两句较普遍。
A: When is your plane tomorrow? I would like to see you off at the airport.
你明天班机是几时？我想要到机场给你送行。
B: Thanks. But don't bother to come to the airport.
谢了。但请不要麻烦跑一趟机场。

2) upset (a.) 感到不爽的，生气的
3) bother (v.) 费心，麻烦
