#9: Try Fake Yawning
I’m not sure that this is one hundred per cent foolproof but if you didn’t have the attention of creepy strangers beforehand it will certainly be a way to get some. Sure, just go around all day doing fake yawns you won’t be attracting any extra stares from anyone at all.
While I do appreciate the sophistication of the method this flaw does seem to be just a little bit too glaring. So I can still recommend you try it out but just take my advice please and try it out sparingly. Only try the fake yawn method if you already have suspicions, otherwise it’s a self-fulfilling prophecy.
