My dad is of the age that he couldve gone to vietnam. Last week he and my sister went to the war memorial as tourists. He was in a wheelchair because hes in bad shap from his alcoholism. So hes sitting next to this other guy in a wheel chair and the guy turns to my dad and asks when he was there. My dad goes "Oh! Seventy!" And then told a few more lies. Its not that hes that senile- hes in bad shape for sure but I think he deliberately lied. Why? I dont know but I thought you could appreciate the story. Btw my dad WAS in the airforce in '70.
