+Q:
+Hi, 你呢兩日有時間講個電話，傾吓用咩模式比較好？
+
+A:
+ok ar, 可以安排，通電話方面夜晚 8 ~ 11 方便嘛?
+
+Q:
+我諗法係，每次上堂之前我會 send excel files 俾你，大概話俾你知我想做乜嘢。跟住上堂可以教我。
+不過可能頭幾次要講解下 IDE, vba syntax etc
+
+A:
+ok ar, 可以的話請預早一兩日 send 過黎 : )
+
+### notes
+
+Q: 不過可能頭幾次要講解下 IDE, vba syntax etc
+
+我會比較傾向我做完，再同你講下點解我要咁做
+如果你係連 syntax 都未清楚的話，咁可以順手睇埋/問埋
+
+因為我覺得單獨 背／記 syntax 係垃圾行為，
+其實 點樣用／幾時用 先係要學嘅事
+
+syntax 你 上網／自己寫寫下果個 code base 都有得抄，
+唔需要刻意去 學／背／記
+
+當然我都可以比個 kick off 你，
+用人話講即係好似燒味拼盤咁樣樣有 D 輕輕介紹一下
+
+但係 in-deep 到你用到果陣時就自然會知 / google
