I have posted this before but it's worth watching again.
Four years ago a kindergarten teacher in Sderot wrote this song for her pupils who were showing signs of traumatic stress (withdrawing inwards, bed-wetting, regression, etc...) after constant rocket attacks from Gaza. These children have 15 seconds to reach a safe area before the "BOOM!" And the "TZEVA ADOM" (Code Red) can come any time of the day or night
This is one class performing the song for the camera but the sirens are sounding all over the south of Israel several times a day and night. It's often the bravado that gets to you the most. This makes me cry every time.
