Hot shower! Checked out of the hostel and headed towards Sindagma Square to find the American Express office. Got a replacement Amex card (mine hadn't arived by the time I left). Found a travel agent, and bought a ferry ticket to Corfu for tomorrow. No boats today, so one more night in Athens.
Spent the rest of the day wandering around Athens. Revisited the flea market at Monastiraki Square, still didn't buy anything, but it was fun to wander through without quite as many people as Sunday. Spent several hours at the Acropolis. Between it being Monday and the rain I had it pretty much to myself. After the Acropolis I wandered around the Plaka area, and then headed back to the hostel to check in again.
Spent the evening reading in the lobby until I was challenged to a backgammon game (which I lost, twice), and somehow I ended up being invited to share in the dinner of a group of French and French Canadians (Qubec). The dinner was excellent, and my French is now much improved, although still a long ways drom conversational. The night ended up with various drinking games (Mexicalli, 3-man, etc).
