why?

Why is it that whenever something big happens things keep popping up everywhere that seem to relate? such as the music video your friend shows you that is pretty much about you at the moment. or the song that comes on that is telling you what you should do. or someone else's blog that's describing the very thing you've just done.

I've done something i'm not proud of, yet it made me feel so happy. Is this what the religious world calls a sin? All technicalities say it's fine, but my heart says otherwise. Why did what happen happen? Why is it that in some way i get what i want but it's not always what i should have had?
