I can't write mandarin!! But I just saw this on fb, it came up at my news feed. It's something I'd like to say if I am well versed with mandarin!

你是我的不知所措，我却只是你的心不在焉。(Simply put, u make me at a loss for words and confused but I'm just a distraction to u)

Impressive, huh? Well I'm easily impressed. :P
