I have this theory or maybe everyone has the same theory as me too. If you love something, anything, so much, you'd do it twice or if you do it twice, it means you love it a lot. I'll always say to whomever I'm out shopping with, if you touch something and walk away but you came back to that same thing and touch it again, you should get it, because if you don't, you might not be able to sleep at night without dreaming about it and regretting it later. If you love a band so much, you'll watch that concert twice and same goes for movies too. If you love someone so much, you'll do it twice too.

The theory is pretty much self-explanatory and I think Bob Marley agrees with me too, "Baby you so nice; I'd like to do the same thing twice, yeah!"
