Mine too. I sometimes wish my committee were more hilly so I'd get more exercise, but generally I'm glad it's so flat. I can mall my route a lot more hilly if I add a mile or so to my route, which I occasionally do if the weather is nice and I'm feeling energetic enough.

Edit: Adding specific data...

According to my Strava app on a recent commute home, I had 73 feet of elevation gain over 7.3 miles. Pretty flat.
