Here in Australia it's really common to hear the abbreviated names of these jobs.

在澳大利亚常常能听到工作的简称。

I used to put my initials, W. M. D. , and someone was like, that's a little bit weird, so now I just abbreviate my name to WAR.

我过去常常把我的名字缩写为 W.M.D.，有人说，这有点奇怪，所以现在我把我的名字缩写为 WAR。

I also included another tag, which gave each box a number because all cardboard boxes look identical. I was careful not to abbreviate the names of items in the lists lest that would mislead me as to the contents.

我还准备了另一个标签，为每个箱子编一个数字，因为所有的纸板箱看上去是一样的。我很小心，不在目录中缩写每一件的名字以免使我认错里面的东西。
