Just got back from my brother's wedding in Princeton, NJ. A majority of our family and friends were from the South, primarily Texas. Most of the bride's family was from up North particularly around the East coast. I noticed a huge lack of hospitality amongst the bride's family and friends. I don't really mean arrogance but it was rare for anyone to come up to me and introduce themselves even though I was the best man. This was experienced by almost everyone who came to visit. Thankfully I went out to mingle but we had to do all the introductions and be the first to say anything. Is this common amongst East to North Easterners?
