I think this is nearly impossible. I made accidental eye contact, mostly when eyes happened to pass one another, and a few times when in conversation with Sean. Walking and talking makes this boundary easier and it's rare to constantly look at someone when on the move. This boundary has required the most concerntration. When asking people in school to borrow equipment exc, I've directed my question at the object. Getting other's attention is tricky and conversation had an underlying distraction.
I told my teacher this weeks boundary last week, and I'm glad I did. It's easy to assume I'm ignoring everyone.
