sign of the times

While driving to the library, the younger three played "let's text" while in the back seat.  They each had a play cell phone and  would proudly announce their texts to one another in the back seat.  All three took on different names.  It went something like this...
"Chelsea, are you on the way to the library?"  send
"yes, I am in the car with my mom, c u soon." send
then my 6 year old son text....
".... MOG!" send
I nearly ran off the road when I realized he really wanted to say... OMG! 
I don't ever remember playing  "texting" - a sign of the times for sure!
