I think it's wonderful when people feel they want to support the troops and their families in unique ways. It is definitely the thought that counts.
Now I have to agree with cdnaviator though. I am not the family of a serving member though. However, if I was, I don't think I'd be up for pen-paling with a stranger while hubby was away. It's definitely nice to have support, but that is what friends and family are for. I think the emotions/situations and whatnot dealt with over a tour are a private thing and I would almost be weirded out by someone random writing to me about it. I know when my best friend was dealing with hubbie's deployment this past winter/spring she tended to want to keep to herself too. It's just a trying time.
Like I said, supporting the troops is great. But, lets not take it too far. Lots of people go away for work for long periods of time. Sometimes I feel like it is really over-sensationalized with the military. Yes it is a unique life, but it is also chosen by the serving member. The are paid to do what they do, and they know what goes along with that career. Sometimes I feel like people make military families out to be victims, and they need all this special attention. I have spoken to many who really don't like that. They are people living a life, just like "average joes". Definitely some different circumstances arise, but no need to feel like they need social programs.
Once again. Kudos to an elderly woman wanting to do her part in support of the troops. People like that melt my heart.
