When you talk to someone for the first time, you want to be sure that you do not say anything weird or insulting to them, since first impressions are everything in society today. Be courteous and show the person your respect, especially if you are talking to someone in your work environment for the first time. Be careful what you say and always keep a respectful tone, listen closely, and respond appropriately so both of you are happy and no one feels awkward around each other for future gatherings.
