Syag > You closed a sefer
PS I don’t think I closed the sefer. That would not have helped, maybe even made it worse. I would usually take a small Gemora volume (just one blatt of Aramaic is sufficient to put me into philosophical mode and then into sleep, so Brochos worked for many years), so I packed either an English sefer or a math one for next trips. Both sefer or math are not really hukas goyim in USA.
