In Lahore, Batul and I wandered around a mosque construction site. After a few minutes, a guard approached us and asked if we were looking for a bathroom. I said that I had never seen a mosque under construction before and thought it was neat... could I stick around? He had reservations about this... not because of the safety of poking around on a construction site, but because my head was uncovered. So he asked me to put on my dupatta (head covering), and then he was fine with my presence.
