That has to be the stupidest thing I have ever heard. Why the fuck would you even ask a question if you know the answer to it? The question is pointless, much like your life.
more than this, feign wanting advise on something that will give the person away. example: if $50 went missing from your house, ask your no.1 suspect if they think you should bother viewing CCTV footage taken outside. i did this once lol (different but similar circumstances), silly bitch was like 'i dunno..there's no point' :D
