'kalo ga ada halangan'??! words that more suitable to say to an acquaintance.

and it IS kinda rude to say that to the person who invited you, isn't it?

well... not always... it's called being honest and informing you of it before hand, rather than saying "I'd come" but doesn't show up later

i better not have that kind of attitude when I'm planning to get married

a very good friend asked me to come to her wedding, and I said to her I'd come if nothing's holding me back...

sei_kun, you're right. it's better to be honest. still, if it was your closest friend, shouldn't you put it as top priority?

that time I didn't know if I'd be allowed to leave the country to go to her wedding

better be honest than be a disappointment

oww.. on your circumstances it is difficult to make a promise..
