Why Do We Memorialize Missionaries?

I've done better emotionally this week and felt strong heading to church.  I got there and saw the program, "Missionary Mom's" were on the program.  I actually thought I would be ok staying and listening until the first mom began memorializing her son.  She told how she never cried until her son left...words straight out of my mouth...and then I felt the tears well up and couldn't control my emotions.  Their sons and daughters will come home in less than 2 years.  Mine won't.  They get letters, emails, phone calls...I don't!!  These are the same feelings I had early on when I had others telling me Gracie was called to serve the ultimate mission on the other side.  They don't say that shit anymore and I wasn't asked to speak with other missionary moms.  Just when I feel I'm getting used to the tide....The only thing I'm used to is the unforeseen wave that knocks me off balance and slams me on the ocean floor.
