You know, things like people walking a mile to return your wallet... It seems like you've gotten a little ostracized at your workplace, and my heart goes out to you... it might be related to your overseas origin, but on the other hand that distance probably means at least they won't go really out of their way. To throw away your notebooks in puddles or anything like that.
