It depends. If they are my friends, no matter who is right or who is wrong, I will go over immediately, calm them down first and I won't pick side. If they are strangers, if it's not danger to someone's life, then I won't do anything, if it does, I will find a strong guy near by to pull them away or call the police. Don't do anything casually before you make sure you are safe.

It's not common for me for now. I have only said one or two times to my mother and it's not face to face, so don't mention say it to friends or coworker, umm but sometimes when my best friend do me a great help, i might say it for fun, but still very few. 

I love them and I know it's important to show your love to someone matters to you. But I think it just make me feel awkward to say it out, we usually show it with our action.

It's not easy for our and our above generation, but it's getting better now. Young couples start to call their child 'baby(宝贝)' and say 'I love you' all the time. I think it will make their child feels it's normal to express love. So it will become more common in the furture.

粵語日記

大家好。咁俾我介紹下自己先。我叫Marcus,而中文名呢就係阿銘。我而家自己學習緊啲廣東話同國語。我嘅廣東話亦都唔錯架，但只不過呢（但同只不過係一樣嘅意思,可以講但係呢...或者只不過呢...）係啲vocab(詞彙/詞彙量)比較唔夠(唔係好夠).我得閒就睇下講國語啲片呀(like(比如/例如) 中國片呀，臺灣片呀)或者係香港劇。我都追下啲美國劇嘅，但現在唔係幾咁喜歡(中意)睇囉！我識講越南話添嘅，就因爲喺越南嗰度出世，同家庭親戚(屋企人)用粵語嚟傾偈。我啲English(英文)呢就自己覺得幾OK吓噃。不過仲有好多啲進步空間嘅。平時就鍾意聽下音樂呀，上下Facebook呀，睇下啲YouTube片呀，練習寫啲中文字呀，瞓覺呀，睇片睇劇呀，廚煮下啲嘢食呀，blah blah blah. 太多節目啦！我仲喺uni(大學)度讀緊書嘅。我major(專業)係化學同生物學，但我覺得生物對我嚟講係比較難啲。佢太係一種好(太)focus on pure memorising(好靠記憶嘅嘢/太靠死記硬背嘅嘢)羅。尤其是係D medical terms(醫學詞彙/術語)呀搞到我都暈toto(暈坨坨) (請你哋italki朋友們幫我教下個toto用中文字點樣寫，merci 晒吓！)。呢幾日過年其實有D悶。。。。
