I am who I am

Someone say I am smart as I know how to manipulate people. I know how to please people that are 'useful' to me by sending gifts to them. To a certain extent, I think presents are useful. But, put in a more appropriate way, those small gifts are tokens of my appreciation. I mean to thank people who have been of great help to me. This is life. Not everyone who knows you truly understand you. That's why we got this word called 'misunderstanding'. I won't bother to explain to anyone. For those who trust me, you will trust me. For those who don't, whatever! I don't really care how you think, serious!
