I saw a lack of capitalization

Context
I did New Staff Orientations for five new library employees today. Part of the orientation is filling out a time sheet on the computer and printing it out to be turned in to payroll. Two of the students typed their names on the paysheet in all lower-case letters.

Commentary
When I saw my students not capitalizing their names, I had three progressively softer reactions:

1) This is bad grammar.

2) This is inappropriate grammar; i.e. there are some circumstances where lower case is OK for names, like for e-mail addresses or if you're e.e. cummings, but this is not one of them.

3) This is a stylistic choice that makes no difference in this context. After all, it wasn't going to keep anybody from getting paid or anything.

I think the fact that #3 was definitely true but I still had reactions #1 and #2 says something about me. Ah well, I notice stuff; that's my job.

So since I do notice, I wonder what typing your name in lower-case says about the students in question. Specifically, is it really a stylistic choice, or does the person not know any better? Actually, that second choice could be divided in two: does the person not know names are traditionally capitalized in English grammar (Yeesh! I hope not!) or do they not know how to capitalize on a computer (still sad, but not as sad)? From an educational standpoint, the answers to these questions are important. Ignorance requires a remedy, but stylistic choices can be the start of a student-teacher dialog on different modes of expression.

I'm reminded of when I taught in a minority-dominated high school in the late 1980s. We used to agonize over whether some of what we were teaching was tantamount to expecting students to deny their native cultures. Over time, I came to believe that my job was to offer the kids the tools to make an informed choice: if they chose to adopt the values and habits of the dominant culture, their lives might be enriched in some ways and impoverished in others. Either way, they go in with their eyes open. Which is always a good idea.

What did you see today?
