Hi everybody.
I have a simple, but very interesting for learners question. How do native speakers say hello and goodbye in different situations? What words do they use in formal writing, in informal emailing and instant messaging. There are clear differences between formal and informal communications, but I am often confused with choosing appropriate words while informal emailing when it's ok while IM'ing, and especially while writing semiformal emails (e.g. to my teacher). I would appreciate if you describe how you, your friends and anybody else write emails and instant messages. I suggest the following pattern of answering:

  • Formal EM beginnings/endings: ...
  • Informal EM beginnings/endings: ...
  • Informal IM beginnings/endings: ...
  • Your comments on using some of them.
