Learning Curve

I'm not the same as I was last year I can't predict who I am gonna be 5 years from now, how it all works out If we grow parallel or separately But then all of a sudden I'm falling in love with Somebody new And you are too Look how we change Same parts but rearranged Just when I think I'm catching on You turn a different shade Not who I met at first But where's the fun in that I'm glad for every twist and turn For better or for worse It's a learning curve You've got a new favorite shirt I laugh at different things but still at you the most And now I speak more self assured And you're more level headed than the you I used to know Oh isn't it something I keep falling in love with Somebody new And you do too Look how we change Same parts but rearranged Just when I think I'm catching on You turn a different shade Not who I met at first But where's the fun in that I'm glad for every twist and turn For better or for worse It's a learning curve
