Teachers find out how much they've impacted past students in heart-warming video

We owe so much to our teachers, but sometimes they can go unnoticed!
The video aims to show teachers what their past students really think about them. Participants were told they were just taking part in an interview about teachers who had touched their lives, but in actual fact, they were about to come face to face with the teachers themselves!
