'conversation-continuation disorder'.

well, basically, 'conversation-continuation disorder'
is like a problem which, some people might have, causes
a communication or conversation breakdown.
and this leads to some problems, big or small, which
is kind of annoying and it might change some things
in your life. and yes, it may involve cold wars.

and i am a victim of 'conversation-continuation disorder'.
and not proud of that.
for me, since young, i'm not a out-going type of person
to people i just know, or towards people i'm not that close with.
so, i tend to keep quiet, if possible, all the way. :)
and to me it's quite a habit..hard to change.
and when people talk to me, people whom i seldom meet and talk to,
i tend to answer straight to their question. like a one-word answer
or a one-phrase answer..things like that.
and since young, i don't find it a problem to me.
but as i grow older, i tend to meet more people, so i should
become more sociable. but for me to become sociable at this point
of time, i find it difficult.
i won't say it's impossible but rather possible if you try hard enough.

so, in order to not make things even worser, i should
try to communicate more. but can someone tell me how to
actually continue a conversation with people whom you're
not that familiar with?
