I was pretty surprised. I think the fact English isn't his native language factors into it - I can see it makes reading harder work, but conversely, if you're working in a second language I would expect you to read more carefully because on the whole aural understanding is harder (maybe not if you're Chinese, I don't know). He's rude as well with a bad habit of breaking into conversations I'm having with other students (or staff members) in the lab with demands I deal with his problem. So I'm thinking poor student, with problems compounded by working in a second language (and possibly being an Electrical Engineer working on a programming project).

Certainly, with the other students, it's clear some of the issues arise from much lower exposure to programming work (and therefore some unreasonable expectations about how long things may take them to achieve).
