First, I'm really don't like to use a plastic bag when I go for a purchase. Thus, when I go shopping with my friend, I will always be a role model to use the eco bag that I have already prepared to use and my friend always asks why did I do so, my answer always is, it is better to change yourself first before you want to change something or other people. I will also tell my friend that the disadvantage to use plastic bags and they also clearly know that. Now, when the cashier asks us did we need the plastic bag, my friend will automatically take out her eco bag and say no plastic bag. 

In the second experience, my little brother always is selfish when he was a child, he don't even want to share something with his family members. My parents got no idea to change his attitude. Thus, I always play a game with him which is what I call a 'sugar game'. each of us has ten sweets and what we need to do is we need to use the sweets to change a better thing from parents, we can persuade our parents in our own ways, the person who got the better value things will be the winner. The value behind this game is if a person is willing to share with others, what you can get is more than what you give. This game is really meaningful because my brother is more willing to share something with people.
