So it’s my Birthday. Wish me a happy one. But please do it selfishly. Do it because you want to get to know me. Do it because it makes you feel good for making someone smile. Do it because you want me to share your Birthday celebration. And lastly do it because your Birthday matter more to you, than mine does, and by offering a happy one to me, you hope, in some way, that same happiness will be reciprocated back upon you.
