Wish him and his fellow Marines well for his tour and for a safe return. Ask him if there is anything from "home" that he or any of his friends needs, these often turn out to be really small and what appear to be really silly things, but receiving then makes a tremendous difference. Stay completely away from politics, I've never known one single serving sailor, soldier or airman that was ever interested in the subject. News from home and family is always well received.

I for one appreciate the job he is doing and wish him well.
