Abbreviations can cause miscommunications ! This is why, my understanding is, we are all asked not to abbreviate when sending messages on the PBS email org.... Imagine how hard it must be for international viewers who don't have English as a first language, to follow some stories... Thay are sometimes left with substantial gaps in a conversation ! I grew up speaking english & sometimes i have no idea what some of you are talking about, I am sure this is more common than people realise.... With some people something as simple as ( I'm or don't ) is even difficult at first, rather than ( I am or do not )... Hope that makes sense ! Steven
