Acronyms have become so ubiquitous in our language that conversations with people in other fields can get confusing. Sometimes it's just funny. Not too long ago, one of my best friends and I were agreeing that we were both doing a lot of PCRs lately... except that in her job (EMT), that's Patient Care Report, while in my job, it's Polymerase Chain Reaction.
Sometimes, though, it's just downright disappointing. Once a month I get an email from HR inviting me to attend EOD* training... but they won't ever let me blow anything up!
*Employee and Organizational Development. Much less exciting than Explosive Ordnance Disposal.
