sorry!?

can a word 'sorry' helps to cure everything?

sigh... saying that!..
makes the person who said that feels more guilty..
and it makes the person who listened to that feels useless and a bit annoyed..

i'm feeling very very NOT GOOD now!!!
i just indirectly helped someone to waste 12.85 pounds??
should i pay back that money?
but it's indirectly...!

ok.. the story goes like this...
yesterday i asked X whether Y can stay at X house for 3 nights with me...
X said 'ok'.. 'very ok.. it's fine... '
I asked so many questions and everything as a precaution... all also OK!...
Y asked X again... and X said OK!! again..
so, I helped Y to book the train ticket and everything.. paid!
Today, X said 'SORRY!! it's not OKAY'

o.O
sorry can't help la omg!!!
now Y is telling me... complaining to me..
ahhhhHHHH!
and i said SORRY sorry SORRY sorry *1000000000000
