On her way to school rushing to be on time Ana slipped and broke her ankle as it turns out. She heard a crack, and it was later confirmed at MIT medical. Ligaments in the foot might be ruptured, too… orthopedic surgeon will have a look tomorrow.
The wall came down after I patched it seven years ago with simply stacking the stones. At the time I predicted a lifetime of five to ten years. Pretty accurate.
This time I dug a foundation filled withe our own gravel and build it with mortar. Decent backfill and some drainage. I am sure it holds for ten if not twenty years.
