One thing I've come to understand is that, the fact that you easily get along with someone doesn't really make them your friend. If you want to achieve a good friend you need to set standards and boundries for yourself and the prospective friend. You need to assess the individual properly before reveling confidential matters no matter how irrelevant you feel it could be. Your purpose for sharing the information might be misunderstood just for selfish reasons.
Nice job dearie.
