I don't get offended easily. actually, I'm more likely to offend others with my no-bullshit attitude. And actually, betaing is helping me de-stress, in a weird way. There's nothing better than breaking down writing and asking why this? How that? WTF? Then keeping some parts and changing others. Sadly, I don't get to do that much with students unless they specifically ask for it (of course, by uni they're pretty confident with their writing, even if they shouldn't be). Mostly I just get to toss around ideas, etc, with them.
