Is everything people do at my expense?

haiz... do u guys ever think abt the things you do? and how they might somehow affect others? even words said without thinking can hurt another badly its just they don't show it cos they dun want u to feel bad and guilty for them... i know i have had my fun at others' expenses too and for that i am sorry... maybe i should just cut connections with these people or everyone else for that matter... maybe the world to all of u out there will be brighter once i've left... to all who read this, one day if u dun hear from me, dun bother looking cos i'll probably not be here... but then agian, most of u know already that i do exist and your search for me will not end in vain. but think before you leap next time, for u may just land on somebody's feelings and thus lose your footing with that person. looks like my expense is nothing to most ppl... particularly some of those closest to me......
