Frustrated..and not in a good way

I realized today that being a lady sometimes means being a doormat, a punching bag, and somebody's crapbag all at once. You can shut up and take it or be a bitch. Apparently those are the only options. Ever since I was a small child, I have spoken out if something isn't right, but now that I am a "grown-up", it is a little tougher to do so. I have a big brother. When we were younger we would get into fights and I would muster every ounce of strength in my little muscles to try and hurt him and he would just laugh and laugh...which would ultimately cause me to become even more angry. I had forgotten what a gross feeling that is until I witnessed it in business! Do people ever grow up? So my options are smile and take it or tell them to shove it up their ass.
