how will u define a best friend

A best friend is someone with whom you share good rapport who understands and supports you in both good and bad times. A true friend is frank and honest with you and whom you can trust. Cheers:)

A person whose always there for me, whom I can trust and will never betray me in any means. Someone who manages to send me a simple hi how are you message even if we're far from each other. Someone who tells me more of my lapses than telling me what pleases me most of the time. A person who laughs and cry with me and responds honestly when I ask something. I have 3 of them fortunately :)
