Kangster asked and everyone just answered "no regrets"
Then it suddenly hits me that there's actually quite some things that I would have/have not done should time turns back. But no. Even if time goes ticking counter-clockwise, the same Jason will still do the same things. That I'm sure...
Then, there really is no point in regretting isn't it? Letting that girl go; having not spent enough time with parents; drifting with some friends; etc etc. I'm sure, they'll still turn out the same.
