Guilt Complex?

On my way to SFO on Monday I sat in an exit row in Economy Plus. At first I felt kind of guilty that as, easily, the shortest adult on the flight I had so much leg room I was able to straighten my legs completely without touching the seat in front of me...

A few hours later with a few hours still to go, I felt less guilty...

Then I walked back to the bathroom and saw these tall, larger men folded into regular seats and I felt guilty again...

Now facing a red eye back to IAD I'm bummed I can't secure the same seat!
