I might be black and white, but when I'm with you,

Yesterday is just another memory ;
One more day you made me laugh so hard I cried .
Unearthing what I thought he took when he left ;
Couldn't have moved on without you by my side .
On my grayest days you brighten up my world ,
Like a rainbow piercing through a stormy sky .
Often only you can keep me from falling ;
Unforgiving to the jerks who've made me cry .
Realizing what's best for me much sooner ,
Much easier than I can do on my own .
You bring out the best in me even at my worst ..
What would I do if you left me all alone ?
One day we may be forced to part ; but if so ,
Remember all the nights we've spent together .
Laughing , crying .. Talking about everything ;
Dancing in memories we'll have forever.
