If in a day I will win a lotto I know exactly what I will do.
First I would give a part of the money to my parents because they raised me and they really deserve it. An another part I would spend to make happy some poor people or orphanes, everyone deserve to be happy , if I am why no't to make others too.
A little part I definitly will spend on a mall trip , I would buy clothes and eat something at the food court. Also I will invest in my education , going to additional english lesson's won't hurt me. The last part I will save for the black days.
