Key concepts
Verbal: Your right hand raised looks like the left side raised in a standing mirror — left and right swap.

Level 2 — Real life
Try standing in front of a mirror — raise right hand; mirror person raises the hand on your left side in the reflection.
Indian real life
Connect this idea to your daily routine at home, school, or the local market in India.
