Dear shan84,
I am so sorry that you had to experience some people's rude behavior.
This is a reflection on them, how narrow minded and judgmental they are.
You should be very proud of yourself for having such determination.
You know, they might be skinny but they are skinny a**holes!
How about ordering some new videos?
Or even better:
How about free exercise videos on youtube?
There are soooo many good ones: from free zumba videos to the traditional exercise type.
Hang in there, shan84!
Best of luck!
