To each word its meaning

Just a small off-topic thread (in memes&games since off-topic doesn't exist... sorry m&g guys) about how I got screwed over by some fuckign engrish.

Context : I am a programmer at a telecom company. We're all french, but we develop in english, since apparently, developping in english is the right way. I agree to some extent, but I still believe that it's a stupid thing to do in a company driven by a 100% french government policy. Now, let's be honest, not everyone has the same level on english (as pictured on forums). The sad thing is that not everyone has the same level of french either...

So, here I am, doing a little tool to calculate how much a certain thing is gonna cost based on a number of factors, one of them being name BillingTimePeriod. So, shame on me for believing it meant a period, I programmed it that way. In fact, billingTimePeriod isn't a Period(time before a recursion completes and the subject goes bac kto initial state), but a Duration(time that the action is taking part).

Obviously, I get flak out of that, for programming wrong, and using my words wrong (period is so not the interval of time between successive occurrences of the same state). Everytimes it happens, I get a small smirk thinking about Griftix that once said he was always trying to get the right words to avoid confusion.

So yeah, that's my story. Any of you guys ever got in trouble because you or others didn't use a word correctly?

EDIT: It's worth noting that period in french is Période which sounds pretty much the same, while duration is Durée, which once against is clearly not confusing. So no, the problem wasn't even poor bilinguality, but simply poor vocabulary. Also, yeah, fuck accents.
