Everyone wants to know things that they have no business knowing. Things they shouldn't, or wouldn't know if the person who "discovered" it hadn't told them. It's the same for love.
If someone comes up to you and asks: "Who do you like?" They are really asking: "Do you love somebody?" and: "Who?" They are rude and arrogant questions, unfair to the receiver. It just hits them like: "spill your guts."
It's completely uncalled for and unnecessary. I wish there weren't people out there like this, but they're there, and I've learned to ignore them. I realized long ago that it doesn't matter what those idiots think of you. It only matters what you think of you. Be yourself! If that man who you're supposed to love comes around, he'll love you the way you are. Don't sweat it, you're not alone!
