Most of the dictionary describes Friends as “A person you know well and regard with affection and trust”. I am one of those people who would say that ‘I could live without food but not without friends’. This is a unique relationship which most of us have. We won’t call everybody we know as friends until we have an affection and trust, based on a factor called LOVE. Who said friends don’t expect anything in return… everybody will expect a return and Friends are no exceptions. The expectation here is the love in return. I care for my friend and my friend care for me. We often pronounce ‘I love you’ to friends to show them that we care and love them. Many times friends are the first person we share any emotion or feelings which we might not even share with our parents or spouse. Why we do this, because we know that they could listen. Most of the people in the world want someone to listen to them and they themselves could solve their problem. Friends are the first choice.
I am happy to have my friends around me always, even though some are staying away physically but not from heart. I love my friends 
For those who know you, it is a blessing to have you as a good friend.

It’s very true…..sometimes, if we don’t get the return as per our expectation, it hurts a lot.
