Sherri, so sorry to hear grand kids hair.
So reminded me of my first husband, who was Navy also.
All three of my boys went for the required visit, all 3 came back with buzzed uneven haircuts. Reaction was about the same as yours. Good thing he just dropped them off, & didn't come in.
Was totally fit to be tied, wanted to buzz his...well whatever.
Oh, wait a minute could it have been my ex? He's only been married 7 times now.
