No, 50 minutes. xdOver 210,000 people have died in Syria and more than 500,000 in Iraq, yet you don't see people changing their profile picture to the flag of Iraq/Syria. You also don't see anyone being silent for 1 minute for either of these countries. If 9/11 and the Paris attacks deserve a 1 minute silence, then these other war-torn countries deserve 10 minutes of silence.
But forreal, no, be silent on your own time, people got shit to do. :|
