Wandel!! How did you know?
It is a little odd that he had come straight from Saudi Arabia
... also known as "the mother of all swamplands". So that makes total sense!
Thomas, he was just at high school age when they moved back to the States. Dys didn't know anything about US teenagers or American schools, so he spent his time sitting under a tree reading books for most of those four years.
Glad you're feeling better--and the best is yet to come.
