话虽如此,每家公司都有自己的关于在电子通信所需的正式程度不成文的规定:制定它们是什么以及跟随他们。
Having said that, each company has its own unwritten rules about the degree of formality required in electronic communications: work out what they are and follow them.
Don't think too hard about unwritten rules like 'oh I went on a date so now I wont contact him for 3-4 days' If it went well contact the person the day after!
