Today's post is brought to you by the letter S. S is for …

• School, because this is the first time I have been able to walk my kids to the first day of.
• Shavasana, because that is the pose of yoga I was doing today when school started at the school I no longer teach at.
• Silence, because that is what I hear right now in my "office" in our living room.
• Start, because today is the true start of Flipping Physics.
• Scared, because I feel scared.
• Sad, because someone else is teaching the students I would have taught.
• Smile, because I am excited.
• Surreal, yes, this is all quite surreal.
