LOL!  Tks, Krissi!  I was trying to throw a curve ball to see if anyone could find a way to use Rang as the first word of a sentence!  Well, your grandma came up with a good one!  
 "Rang is past tense"
 "Rang is past tense" is a good sentence!   Great job, Krissi and "Grandma"!   
And I'll try to be nice from now on!  

Tense muscles drive us up the wall.
