Nothing's quite the same...

In the last week, I've noticed a significant number of people in their pajamas wandering around Evanston. More, in fact, than I've seen in the last two years total. I'm sure this is linked to the opening of Cerealocity, or whatever its name is - the new cereal bar in town, where employees wear pajamas to work and customers eat cereal at all hours. My question is, am I just noticing more pajama-clad pedestrians because I'm aware they might be there, or are there actually more around?
