Well, the great stocking caper has been solved! S10 did not finish putting the stockings up, so it WASN'T intentional. He told me yesterday that he started to put them up but didn't finish (5 stockings and he got distracted at 3! The Ritalin Ranger!)
Also, D18 told me STBX sent her a huge care package at school. Go figure. Army this weekend..ARMY STRONG!
