I have heard “thanks for your service” a lot of times. I always reply with your welcome. The other day I was walking around the U of A campus in Tucson, AZ. I was wearing my Vietnam Veteran hat I got from Sgt Grunt. I heard the thanks from a lot of students. One student came up to me and said “Welcome Home”. We shook hands and talked for a bit. His dad came back about the time I did to all the protests. It almost brought me to tears. So if you see a Vietnam Vet give him a Welcome Home! It feels good!
