I was talking about my day and I work close to Ts office and because of what I was saying T realized I worked nearby as well. I was vague on my application as I am in social services work. Well, with talking about work, etc. T has asked me if I work where I do. I asked why T wanted to know and T smiled and said, "So I can stalk you" with a big grin - not serious

. I told T I did not want to say because it might be T knows my boss, etc. IRL and may not know them like I do. I worry this might make T think differently about what I say/my issues/concerns if T's limited view of the person is different.
I really do NOT like that T knows where I work. I feel like anything I say may be compromised if T knows someone that knows me or if we run into the same client, T gets my paperwork in a referral, etc. What if I had a typo?

Am I being too concerned about this? T tried to confirm the location twice in the same session which bugged me and so I gather T knows now from things I've said even though I've never stated the title of my office. Oh well. It does bother me, though. I guess I should bring it up again. Or should I?
