The shoulder bumps are intentional. I guess there are a lot of angry women out there seeking to bully men and, since I'm not that big physically, I am a good target. I have a friend who is shorter than me and his attitude is "if people want to walk into me they are welcome to." I guess he thinks there is nothing that he can do about it. However, the problem seems to be increasing and, with my bad feet, there is also a physical limitation involved. Is this behavior all part of that "mean girls" behavior / mentality?
