I apologize if you read this yesterday, but the management had a finals-induced FAIL.
I have a weird minhag that no one else around me has: I don't place religious books where people sit. I hear this isn't an uncommon minhag in chareidi circles. However, modern orthodox Jews generally seem to think I'm crazy with such a silly minhag :)
This minhag leads to awkwardness, but only on my part. The source for my minhag comes from very early in my Jewish career, when I enjoyed some Shabbos hospitality. It was my first "real" Shabbat experience. I was on my best behavior, staying with a family I'd never met before. They had small kids, and I was about 21.
I was minding my own business, holding a siddur. And then I made the mistake of sitting it on the couch next to me. Suddenly, a 5 year old is yelling at me! Thankfully, the mom overheard and came to explain to me.
To this day, I get antsy whenever anyone takes a Jewish book from me. Especially in shul with the Chumash, it is inevitably placed on another seat. And I sit there, awkward, with my mouth hanging open. I don't know how to react, so I just let it go.
