When you have a birthday you always get some presents, because it's YOUR birthday , but sometimes you are invited to other's one and have to think what to buy.. so what do you prefer to do?
i like to recieve presents, especially unexpected pleasantly surprised,
in fact, i think u are very happy no matter is recieve or give other present.
when you recieve presents, ur happy is come from the present and that person who take care u.
when you give present to others, ur happy is come from reciever's happiness.
in a word, these two kinds of people are happy.
