Rock collection

This is for Tiny Tuesday, my son used to collect rocks and he gave me this one knowing I like to collect them as well. 
Today's State of the Union speach made me think of diversity in general.
Not necessarily having to think the same way but learning to help one another to make this world a better place to live. Anyway, my tiny rock collection is to me a visual thing of what I got from this speach. Each one has its own beauty, its own uniqueness, all of them are rocks, and even though they are different, they complement each other quite well.
