I successfully dropped Alex off at the airport shortly before noon, and he's currently en route to Philadelphia. I'm so thankful he had a mid-day flight so that we could enjoy some last moments together - drinking coffee, eating homemade pancakes, and turning around halfway to the airport because he brought MY passport with him rather than his own. Thankfully we caught that with enough time to get back to the apartment.
As for me, I'm going to the pool to enjoy some R&R. More news here once Alex arrives.
