This song is a few years old, maybe more. The video goes like this - Its about a guy who gets bullied at home, at school.
The video keeps alternating between the band playing in a recording studio and this bullied guy's life.
There are many scenes shown -


1) The guy is sitting alone in the school during lunch break and has food thrown on him
2) He goes to a supermarket, leaving his cycle outside, a group of guys come in a pick up truck and mess up his cycle
3) He is at home and his dad is repairing his scooter outside (or maybe he is repairing it himself) and this guy gets scolded
By his father
4) This guy is writing a letter
5) Towards the end, he is being bullied by some guy and a girl comes and stops them from hitting this guy.


That's all I remember!
