Well, I'm an INFP. I'm the only NF type that can drop the NF in their 4 letters and end up with just plain I P. Get it? As in... I pee? Heh.
Now if thats not light hearted, I don't know what is.
Also, If you want to lose weight..... screw diets.... just read this very post and you'll feel light hearted and light brained! :wink: (God, do I wish I could force more cheesy expression into these smilies.)
Sorry that was stupid, but I just had to say it.
Anyways, theres my contribution.
