This is my 2nd day of my experiment in saying 'yes' to things that I usually didn't do. So, on this lunch time, I ate together with my friends. Because at that time i didn't feel so hungry, i refused to ate all of my lunch. Then one of my friend asked me if she could ate the left over. I let her ate all of the food. Then, she end up treating me a hamburger. Maybe if i said 'no' to her, she wouldn't treated me a food.
