I look depressed, because I am depressed.

Hi Hnoy, whenever I am sad I look at this song on a video clip called 'Shaddup your face' by Joe Dolce and I'm happy again. Try it! It's a classic 80's comedy song. www.youtube.com/watch?v=sFacWGBJ_cs

Now I'm really depressed when I see new questions which I've already asked or answered. Not to mention some silly ones :) p.s. silly ones not refers to your question Hnoy. sorry I was not quite precise

I look depressed because I wasn't the one who first answered your question... how sad. :)
