I'm not sure what to do. I have a friend that I met at work. At work she is the nicest person ever. She is about 112 pounds, while I on the other hand out weight her by 100 pounds. While she has never treated me wrong to my face, I just came across a blog she wrote where she finds fat people disgusting. She thinks they're lazy,etc. I can't help but think she thinks this of me. Should I ignore it? What should I do? Now when she's around I know I will question everything I put in my mouth.
If she didn't give you the link to check out what was on the blog, then you should ignore what she has said. Her definition of fat might very well be totally different from yours. Plus, that is her personal opinion, as misguided as it is. I believe that people's feelings are shown in their actions, meaning if she thought those things about you, she wouldn't be friendly. I think she would be polite and distant. Since she isn't, obviously she doesn't think that way about you. I would disregard her statements and deal with it if and only IF she happens to say this to your face. THEN, by all means, bring it up and have it out with her.
I would keep a friendly, professional relationship, but be weary. She sounds like she has the possiblility of being a bit two faced and shallow and that is definately not someone I would put a whole lot of trust or friendship effort into. Take it slow with your friendship with her.
Do you socialize with this person outside of work, or is your only contact at work? If you only see her at work, then it could well be that she is supressing her personal prejudice in order to be professional around her co-workers (as she should).
If this is something that really bothers you, I suggest you ask her about it. But be prepared for an answer you may not like.
I also want to add that, while she may think those things, she may see things differently with you. Maybe her seeing you and all the work you are doing to improve your health has lead her to alter her thinking. I would take it with a grain of salt, if she didn't want to befreind you for those reasons she would have kept her distance.
