Our sale of the house has now been completed. Keys have been handed over to the new owner. Nothing more to do, except look back and wonder if I could have done more for my parents.
Answer, yes. Technically you could always do more. Practically though it's not that simple.
Also completed is Block One of my OU course. Now I've moved on to Block Two. I posted my first assignments up on the forum today. I've finished a couple more, but I'm not ready to show them to the world yet.
