regional differences

Coming across the popvssoda web page recently got me thinking a lot about the regional differences in how we were raised and to a greater extent how we will raise our kids.

I used to call everything "pop" but as i drifted eastward started calling everything soda. I still do now, but to be honest i'm not sure what Rohan will end up calling it. Will he be confused at an early age since i have no idea what to call the fizzy drink? If we continue our nomadic lifestyle, will it help or hinder his development?
