What to Put on Parents' Gravestone?

I have to decide by tomorrow what to put on my parent's gravestone. They are doing one together. Any ideas?

In many ways the process of deciding what to engrave on the headstone - matzeiva-  is part of the spiritual process.

While planning this for my parents not so long ago, the process went very deep. What words might convey the "who-ness?" of your parents for you? For others involved?

1. We included the traditional acronym .ת.נ.צ.ב.ה. which is customary, but not obligatory. These letters are an acronym for the Hebrew words תהא נפשו/ה צרורה בצרור החיים (t'hay nafsho/ah tzrurah b'tzror hachaim), "May his/her soul be bound up in the bond of life." This paraphrases the words that Abigail told King David (I Samuel 25:29): "But my lord's soul shall be bound in the bond of life with the L-rd your G‑d."
 
2. We had their names and dates in life in English and Hebrew side by side (added dad when he died nine months after mom, as he exactly predicted) almost a year and a half ago)
 
3. Besides the name of my father, the medallion for him being a veteran of WWII (most engravers have these bronze pieces.)
 
4. The overarching phrase that came through a long processed family discussion toward consensus. I don't recall exactly what we chose; for our father something appropriate would have been: "Beloved, generous, loving & kind!" For my mother, we put the phrase she always told us "Be gentle sweet and kind" (some double headstones allow for a different quote for each person) 
 
5. The border was of two batches of leaves of myrtle representing the dual Remembering the Sabbath and Keeping the Sabbath as described in a famous Jewish story about Rabbi Yochanan ben Zachai.
