nope, u werent out of topic, appreciate ur comments 
i agree that having different group of friends is good too, where u
can do different things wif different groups. add more colours to
ur life.
to me, friends r hard to come by. of all the 3 million population
in s'pore, why do i choose u to be my friend? what brought us
together? i call this yuan2 fen4 (what's the english equivalent?
fate? destiny? i hope u understand what i mean).
and what makes a friendship last for many years? a question that
everyone shud sit down and ponder.
to me, i cherish those true friendships, especially those last for
many years one. i still can go out and make new friends, but no
matter what, my old friends still stand more weight in my
heart.
ur suggestion of taking this as "a bid to change urself, all u have to do is
just think that u are spending time with ur frens, not just doing
the activity", is something i tried to keep in mind. for
those i declined, were usually becoz of distance constraints (i
stayed in sengkang, whereas most of my friends stayed in the west
side of s'pore). but that doesnt mean that i dont enjoy their
company!
true, there was a period of time where i travel all to way to the
west side of s'pore and spent the time wif them usually till after
midnight. and what kind of public transport is still available
after midnight? and how much money i gotta spend juz on transport
alone? and can i afford to do it like 3 or 4 times a week?
u mentioned this before: it COSTS too much! and usually i have to
opt out or look for alternative activities. and when my alternative
activities involves female friends, wud i be labelled as chee hong
or horny?
and ur point on "entertaining" (or eng siu in hokkien), i dont do
that to friends. i dont go out wif ppl juz to make them happy while
i "suffer" (e.g. burning big hole in my pocket, involves in an
activity that i dont do or i dont like).
