I was at Mass this past Sunday, and there was this gentleman, who appeared to be in his mid to late 20s, who seemed overly-interested in other people Mass. My sister would use the phrase "nosy." He examined everyone who sat down in the pews around him, and made disapproving looks and sounds from time to time. At one point he actually pointed at a new girl who was Mass and shook his finger at her. As soon as Mass was over, he turned on his iPhone, and began typing furiously.
