Tainted Meormies,,,,

When people die, there spirit lives long in the memories of those who remeber them. For those who do great things live forever because the things that they did in there bodily life are treasured and retold to others. hit's the phrase "Don't speak ill of the dead" however just as true theres good in everyone there is also bad, which is perfectly okay in bodily form. but it really burns me up to hear my grandmother speak ill of my dead mother. whenever me and sister do anything that is consider bad in her eyes she her favorite line seem to be " you just like your momma" or you gone be jus like yo momma" so my question to the blog world is, How will my mothers spirit live long if she continue to taint my sister and I memories?
