sometimes when i came across some other ppl's blog knowing that they are happy, i feel happy for them too. even for those whom i'm not close to or i don like.
i like to use the smiley face emoticon on msn. don like the sad face. its quite irritating when ppl keep using it esp. on their ps. when u talk to them, you;ll see sad faces again and again.
i think it 'll sort of influence other ppl and affect their emotion too.
SMILE :)
