Finally I won't go to the dive trip

I have spent to much money for the last 4 weeks. I'm doing a trip this week-end and I'll probably go to North-Vietnam with Thomas for a week during the recess week in September. It can't afford whatever I like (sounds like I'm just discovering it...). Anyway it would have been a S$468 trip whereas the return flight for Hanoi is about S$ 150....I'd rather to go to Vietnam and to spend some time in Ha Long Bay.
