On our trip along the coast from Rio towards Sao Paulo, we had a brief stopover to say hello to Christine from Theorema Egregrium. The below photo confirms once again that I always look stupid on photos, so please excuse the expression on my face.
From left to right: me, my husband, Christine, her husband. The photo was taken by her lovely son, Pedro. (Click to enlarge, and see Christine's post on the event).
