For me.....we are all here to learn lessons and teach lessons...we may not always understand them but that is the scheme of it all.....I often think about what ifs too..
But hind sight is 20/20, and we can't change the should haves, could haves or would haves....
Tomorrow is a new day....start again...and try to be the happiest we can be...love and friendship is all that is true...........
