Many arguments could be avoided if people took the time to understand what the other person meant.

I've seen this happen in medical charts. For example, on a cardiology unit, doctors track creatine kinase (CK) as a marker of heart tissue destruction in a heart attack to verify the diagnosis of myocardial infarction. In medical shorthand, we write "F/U" for follow up.

Now imagine the shorthand for "follow up creatine kinase."
