What do they mean

Growing up my parents would teach us words and what they mean. I am now wondering how a state that is only 10 hours away have been taught other word like: My friend Shannon will call and say let me know when you get here and I will open the bay, okay but what is a bay? It's a garge door. And in Nebraska if you say something about Bible School we all know what we are talking about, not here if you say that they all look at you and say what is that, so you need to remember to say Vacation Bible school or VBS. Then there is the word slider that is patio door, and we don't have interstate here but we have hi-ways, and if we say the interstate they look at us and say oh you meant to say hi-way, NO I called it what the real name for it is. Then there is the name thing you are always refered by your last name so there is no need to give your kids first names just hope you have an easy last name to say. So who is right well of coure it's us because ours makes more since. oh yes one more if you tell them you are going to make chili soup they laugh and say you know you just need to call it chili everyone know what you are saying. Okay it has been fun at times when we are all saying this but with different words. So you all can let me know what you think their words or our words.
