Right, I do think he is being a tad hypersensitive to what could actually happen from a Google search, but he did lay the boundary. I think the last thing you did was totally innocent and not you snooping. If something like that happens again, don't tell him, it isn't you snooping. But if you do the type of research you did before, that is a clear boundary violation. However, because he is wary of you from last time, you'll never be able to explain the difference.
