I don't recognize the number but it's a suburban area code so I answer with my usual " This is Snoopy " ( work habit ) . He's like " Hey there ... " ( god the voice sounded great on the phone .... yum ) and for a second I wanted to play the " um ... who's this ? " game but I didn't . 
Question: Why don't I recognize the number ?
Because I haven't seen it before .
