It's so right. I guess you can't or shouldn't classify experiences by good or bad, because, like you said, they're all meant to be and they all help us grow somehow. Experiences, though, can be hurtful, meaningful, meaningless, happy, memorable...but that's just the effect they have on us individually, the effect we allow them or make them have on us. What I mean is...they're definitely tough experiences in life, but they aren't bad or good, they just are and the important thing is for us to make them into something profitable, no matter what, because you can always learn something and you can never learn enough.
wise words - you are so right! all the best for you in madrid an greez to max!
