The other side of the "stolen valor" coin (i think?

A guy a couple years older than me and a badass since high-school did 2 tours in Vietnam as a marine grunt. I'm sure he saw some horrible shit and risked his life almost daily, we heard his stories when hanging out at the VFW.
But as he got older and maybe his mind was going, the stories became more "spectacular" with him as the hero doing unbelievable things, obviously made up by him. The others around the table would do eyerolls and excuse themselves from the table.
Such a sad end to a guy who was brave and committed and still deserves respect.
Hope you vets are having a fine Monday!
