shocked beyond words

was just chatting with my lab partner dean just now... she was mentioning about her close fren, abel... always see him with her in lectures last time... and i always tease them being a couple... when she asked me, do u rem him? i thought its gonna be some good news that they finally got tog? but she just told me that he passed away... -committed suicide- though i believe some point in time, everyone would have this kind of thought going thru' in their minds, this still come across rather shocking to me... maybe cuz recently my colleague's dad passed away due to sickness, i was already feeling bad for her... why do people choose to give up their lives so easily? haiz~
