["I'm a teacher. and school starts back up in just 2 weeks.", 'COunting down the days, eh? How was your summer?', "I had a great summer.  I'm feeling really good about this coming year.  Teaching the same grade for the third time."]
That's awesome that you get that continuity. More teachers would succeed if that was available to them. Good for you!
School starts back in 2 weeks.  I'm feeling good about having taught the same grade for 3 years now.
