Both excellent suggestions. Especially since plenty of people are BORED by work/computer talk. The mold might lead to too much shock and you'd end up having to explain stuff.

Or say it's the heating systems for your apartment and the landlord locked it so tenants wouldn't tamper with the thermostat- that's my best suggestion. Grumble about the landlord not trusting anyone blah blah blah and turn the conversation to other peoples' landlords.

Oh... and unplug the humming stuff while company is there!
