Grrr. moment

I went to Safeway with my sister and parked in a handicap parking space and had an older man tell me that they monitor these spaces. I responded with "I know, I am handicapped." Maybe I don't look it - maybe he thought that I was taking advantage of the system and misusing the handicap placard. But it made me mad and then upset. That was one of the main reason why I didn't want a placard in the first place because people don't know and most of the time I don't look disabled. The ironic part of the whole morning was I had just finished the last day of my infusions.
