First, apologies for the tardy response. Life got unexpectedly busy for a few days.
Second, I take your drift that it’s as minimal as possible and perhaps not too dangerous but my personal heebie jeebies wont allow me to think of something going in my skull as anything other than four-alarm huge.
But I’m not a veteran that’s been through his life...
Lastly, I did some rough looking and every source I found for a one week recuperation eventually went back to Mitch McM’s office. Wishful thinking on his part? It seems like the family expected longer.
