Be smart and respectful
Many people do not know how to start communication. It is really the most difficult step. But there is a fairly simple way to help deal with this problem. It is not necessary to focus on getting acquainted, talk about something neutral: about your work or urgent matters.
Do not get too obsessive flirting. Your companion must be comfortable, try to avoid too intense moments that people did not feel like the interview. But do not be too vulgar. Also remember that you can offend people or too vulgar direct flirtation.
Start small, ask simple questions about how the day went, that was his guest for dinner, as the name of his favorite singer or the name of your favorite artist. From these points is usually very easily fastened conversation. But do not stay too long in this topic, as it can quickly become bored.
