For more human interaction, I walked into a small macaroon shop to buy a friend some birthday sweets. Alone but for the store clerks, I fumbled to take them off, find a place to put them on the small counter and get my wallet out of my bag.
"Sorry. You're the first people I'm interacting with wearing these. I don't mean to be a jerk," I told the man and woman at the counter. I took off Glass for the same reason that I take out my earbuds when I am talking to people. I don't want to appear like I am not paying attention to them.
It was fine, though. The woman thought Glass was cool. The man, he might not have, but he didn't say anything.
