Five. That's how many people that I'll answer my phone for.

That's not enough what if someone's calling to tell you you've won a contest or a Nigerian prince needs a favor

I usually leave my phone on vibrate and ignore numbers I don't know if they really want to contact me they can leave a voicemail

I'll answer as long as I know the person or can confirm they are who they say they are

I always answer an unknown number with my best impression of a black or asian voice. And if it's a legit call then I apologize but if it's not then I continue.
