Catherine went to daycare today. Debbie told me that she "never naps" any more, she just rests on her pad. That's another sign that she's growing up.
Mark stayed home all day. Cynthia tutored him on his US 4th Grade maths: the topic was "breaking up." I guess they worked on problems like 28 + 32, which can be re-distributed to 30 + 30. Same answer but easier to add in your head. Mark said it was "easy."
Mark and Catherine dropped Cynthia at the airport late this afternoon. She's taking the long flight back to the USA tonight and tomorrow.
I worked on a presentation for the Leadership Forum at the University of Stellenbosch Medical Campus (Tygerberg). The topic will be Sustainable Campuses. I also had a very interesting meeting with someone from the Stellenbosch Municipality regarding the potential for hydro power from the water reservoirs in the nearby mountains. I think I will assign a group project on this topic for my upcoming hydro class.
Because Tracy was driving to the airport, I left work early to pick up Catherine. On the way home, Catherine asked "Where is Aunt Cindy?" I said she was flying back to her home, and Catherine said "I want her to stay. I like Aunt Cindy."
