John said that I should use smelled instead of smelt. He said smelt was wrong but I always use smelt so....of course, a debate ensued until we googled it. This was the best explanation we found to why I would use smelt and John would use smelled. Apparently "smelt" is considered British English and "smelled" is considered American English. There is a lot of verbs that fall in the category and strangely enough I usually use the "t" ending instead of "ed" like John.

Most Americans will agree that at least seven of these nine are regular. I have lived my whole life in either Philadelphia (between New York City and Wash., DC), Seattle, or San Diego. It seems to me that the BE conjugations are most likely to be found in the Southeast ('South'), here and there in the 'Midwest', and in the Rocky Mountains (i.e., cowboy country).
Gotta love the Rockies (and tons and tons of British literature)...ps John is still upset that I would use smelt in my post ;)
