I don't like being surveilled

There's a van that's always parked around here, with "Survey Solutions" written on the side. While it might be perfectly innocent, I prefer to believe that it's actually some shady government agency surveying my every movement and using an elaborate double bluff to try to cover its shady activities. I need to invest in some kind of lead-lined windows. Which will also help with insulation, it's cold around here at the moment.
