Southern Comfort rules apply. Though Mecklenburg County has grown rapidly and taken in many thousands of "transplants" from other parts of the nation, it is still relatively slow-paced and polite compared to many other urban areas. This is particularly the case in smaller towns like Matthews, Pineville and Huntersville.
BE WARNED: Locals have a good relationship with newcomers they have little choice, but they do not like being perceived as "hicks" or "bumpkins". An extremely common complaint is that outsiders tend to compare the area unfavorably to other towns, which may unintentionally come across as condescending or rude. If you compare Charlotte or its surrounding areas to your hometown, be careful to do so graciously so as to avoid this impression.
