My best friend is XXX.He is tall and strong,which makes others feel reliable(/which gives others a sense of security).He is very kind and friendly to everyone.Whenever his friends have some troubles,he will help them without hesitation and require no rewards.When you have something weighing on your mind,he will be a sincere listener who can comfort you and give you suggestions.In my mind,he is just like my elder brother who is trustworthy forever.
