I'm sorry to hear about your loss. It is difficult under any circumstances.
Once both my parents passed there was an inheritance to divide between 3 of us. My younger sister and I always encouraged our parents to spend and enjoy the money they had saved throughout the years while they could. I also know that it made them happy to do one last thing for us. Since I lived in the same town and the cemetery is close by I took a portion of mine to buy a heavy granite bench with the family name carved in it and placed it next to the grave site. It has given me a nice place to sit, talk, reminisce, and thank them for all they did for me.
