shaken, not stirred

clearly I am making a bigger deal out of this than necessary but I really need to unhook myself from this thing I'm all hung up on...

I know things.
I know that the sky is blue due to Rayleigh scattering
I know that the force of gravity keeps me planted on the ground to and from work each day, and keeps me snuggled in my bed at night.
I know that numbers don't lie
I know that sometimes you can be one size jeans one week and a different size the next.
I know that in his own way he cares about me but not like I care about him
I know that I prefer blue ink over black
I know that I drink to much
I know that I like ice hockey better than football games but watch the former more than the latter
I know that once a year the earth revoles around the sun
I know that I scared to death to open up to someone in fear that I will have my heart broken again.
