I've thought of telling that guy that wanted information why I was blocking him, but I'm not sure I have the energy for it. When I told that other woman I felt like she was using me, she wasn't even capable of giving a real apology.
The stupidest thing was that the information (if I had it, I didn't) would be absolutely useless. I hadn't worked for the company in over a decade. I did consumer goods market research. As you can imagine, trends change quickly, so decade-old information would only serve a purpose if someone was looking for historical data. He seemed to have a general idea that I had left the company quite a while ago. I had worked for a mutual acquaintance for a while after that, and I'm sure he got word of that.
I just had to approach a former colleague that helped me create my website about renewing the hosting and how much it costs. Even when contacting her, I took the time to ask about how she and her husband were doing first. It just seems rude to start off with, "I need this from you", and then put in a lame, "by the way, I guess I should ask how you're doing."
