One can be a true friend by accepting you friend for who he/she is, that includes all of her differences and shortcomings as a human being. Always be true to your friend, whether in person or when he/she is not there. Never backstab your friend and when you would have problems, never go a day without talking to him/her. sort whatever problems you got. Lastly, treasure your friend. treat them as your brother/sister and when you do these you sure as heck are a true friend :)
