During a recent trip to a hotel, we had the opportunity to ride in a crowded elevator.  DS was standing near the button panel.  An elderly couple was watching him and made an indication he could press our floor before they chose theirs.  
I was a proud mom when DS spoke up indicating the panel and nodding for them to go first, "No, please.  I insist."
I couldn't help remembering back when DS was still being strolled around and was 
T-E-R-R-I-F-I-E-D of going into elevators.  What a long way from the days of screaming, "No! No! No!"
