Tsk. Sorry Twitter Followers and Facebook Friends who tweeted and posted this question, but I beg to differ. It is, for me, too stubborn to give love and expect some to be given back.
To love someone without asking for a return is more important. It's the basic. Love is free, you can give it away to anyone. To be loved is only a reward -- a hard-to-earn reward. You have to show how much you love that someone till she falls for you.
For me, the metaphor has been wrong. It should be that LOVING SOMEONE is the WINGS that makes us fly and TO BE LOVED is the WIND that keeps the flight easier and worthwhile.. :))
