I need a little help ... I'm retired and financially my sister and I are sadly trying to prepare for this and just to bry him near my mom's plot is over three. Thousand dollars and the wake and casket will total over Eight thousand dollars ... I never ask anyone for anything I am not able to afford this and if possible every little bit helps thank you and forgive me I have no one else to turn to ...
