Yeah, definitely!
When I hit my head against some crap pile my life is crowded with, I always ask to myself "how could I end up like this?" I had chances to live better, but I let them go. So I groom about it "how could it happen that I became what I wanted NOT to be". Add that for me it is not 5 years but 20 years later, and you get the point.
Yes, I do have songs that remind me about times when all the chances were intact. And I have new sad ones (hell, I wish self pity was not THAT creative )

Now, coming to Titanic, the love story dind't strike me at all. I was overwhelmed with the anguish all the people surely suffered knowing they were doomed, anticipating the drowning. And the feeling of being trapped in a corner, in a dead end, with water climbing at your ankles...
Well, that was a great movie, and I will NEVER see it again

Every day is a new start. I don't believe an ounce of it. But let's watch more comedies
