what woul you do

I will tell him frankly that I don't like what he wanted me to do. Its better to express myself what I like & what I do not like if he cannot accept it so that the better if he will not be my friend anymore.

..hi.. well, for me, the mere fact that you are friends already is your opportunity to decline whaever he asks you to do if it does not go with your heart.. I mean, in my own experience, I can frankly tell my friend that I don't like this or I don't like that because it isn't good.. because no friend will ever put you into something that you don't want to.. So for me, explain to him why you don't like to do it and if you're his friend, then he will understand.. but if he won't then maybe you're not friends at all.. just a mere acquaintance..
