还不确定。我本来答应陪你过生日，现在突然改计划，心里挺过意不去的。

Hái bù quèdìng. Wǒ běnlái dāying péi nǐ guò shēngrì, xiànzài tūrán gǎi jìhuà, xīnli tǐng guòyì bu qù de.

I'm not sure yet. I had promised to spend your birthday with you, so I feel quite bad about suddenly changing the plan.

确实轻不少。我再看看接口，就决定。

Quèshí qīng bù shǎo. Wǒ zài kànkan jiēkǒu, jiù juédìng.

It really is much lighter. I'll check the ports and then decide.

她希望半年以后再决定要不要正式换工作。对她来说，工资重要，但是长期发展和自己喜欢做什么也很重要。

Tā xīwàng bàn nián yǐhòu zài juédìng yào bú yào zhèngshì huàn gōngzuò. Duì tā láishuō, gōngzī zhòngyào, dànshì chángqī fāzhǎn hé zìjǐ xǐhuan zuò shénme yě hěn zhòngyào.

She hopes to decide in six months whether to formally change jobs. For her, salary matters, but long-term development and doing work she likes are important too.

那我先看看天气预报，再决定时间。

Nà wǒ xiān kànkan tiānqì yùbào, zài juédìng shíjiān.

Then I'll check the forecast first and decide on the timing afterward.

不同茶馆的用具和方法可能不一样。如果不确定，可以先问工作人员。

Bùtóng cháguǎn de yòngjù hé fāngfǎ kěnéng bù yíyàng. Rúguǒ bù quèdìng, kěyǐ xiān wèn gōngzuò rényuán.

Different tea houses may use different utensils and methods. If you're unsure, ask the staff first.

不一定。不同地方、不同家庭习惯可能都不一样。

Bù yídìng. Bùtóng dìfang, bùtóng jiātíng xíguàn kěnéng dōu bù yíyàng.

Not necessarily. Habits may differ from place to place and from family to family.

不确定是不是普遍情况：‘我听说……，但不同地区可能不一样。’

Bù quèdìng shì bu shì pǔbiàn qíngkuàng: ‘Wǒ tīngshuō…, dàn bùtóng dìqū kěnéng bù yíyàng.’

If you're unsure whether something is widespread: ‘I've heard…, but it may differ by region.’
