Yesterday, a grad student from computer sciences showed up to the lab to update our software. The lab was closed because the director and her deputy are away. I offered to open the lab for him but he primly replied that it would be inappropriate. He thought I was a grad student.
I probably should be annoyed that I wasn’t recognized as an important figure of authority that I am but I was very pleased. At my age, it’s more enjoyable to be seen as young than as important.
