Once a boy asked god that how can he make the best friend of himself.

With a smile god replied-”My Child! Not only you but each and every person on this Earth needs a best friend .The best way to make a good friend is- 

Taste him/her-See whether he/she is perfect for you or not

Test him/her-To check whether he/she can be trusted or not and given the name of a Friend

Trust him/her-Now You can completely depend on him if he/she has passed your test or not

If he does pass your quality tests it will mean that he cannot become your friend ever.
