Seoul is a very large city and has many people living in it. So we never expect to see anyone we know on the subway. Yesterday Jessica and Linda were in a concert and as a bunch of us were on the subway headed in that direction. About half-way there at another stop 4 SCS students got in the same car we were in (there are about 12 cars per train). Jessica had told her kids she'd give them 5 bonus points if they came. It was fun teasing the kids because they all pretended they did not know us. I had to take some pictures.
