I&#x27;m pretty sure (3) is a generational thing. I and plenty of 20-somethings I know won&#x27;t answer their phone if they don&#x27;t recognize the number, yet my parents get up and run for the phone when their landline rings during dinner time. When someone unknown tries to reach you their default mindset is &quot;But what if it&#x27;s an emergency?&quot; and ours is &quot;It&#x27;s probably spam&quot;
