Frankly! I never actively participated in CS in-spite of being an avid traveler. Presumably because I stay with my parents and travel frequently. However I am open to host once I have my own abode. CS overcomes the barriers of cultures and distances of the world bringing together strangers to share a part of each others lives and experiences. When a stranger opens doors to their home and shares the warmth of their company. It's like spreading goodness which returns manifolds.
