First Full Day of School

Today was the first full day of school.  Yesterday was a half day.  Someone asked how his day went so I want to report that he got off the bus yesterday with a big smile.  However, today he fell asleep on his way home.  The driver is being so kind and working with him.  He is one of the last to get off in the afternoon so she just woke him when she got here.  Not sure why he is so tired these past 2 days.  Perhaps too much anxiety with school starting.  But it is cooling off.  We are suppose to be in the 50s tomorrow morning.  I wonder if the barometric pressure is acting up?  I'll report this to his teachers.
