I don't believe they will be in Teheran.
I've been away from the computer all day and I've been biting my nails worrying about tonight and tomorrow morning. It's all going to come down to how courageous the vast majority of the population is. If they get out there with the kids, it's going to go and go big. If they stay home......who knows what can happen.
If they're going to stay away from the protests, they can at the very least not go to work. That's still more dangerous for the students, but it will send a message. I'm praying for the courage option.
