-Forgetting to flush at the homes of friends and family, out of habit from the strict "If it's yellow, let it mellow." policy at my own home.
-I unloaded my clown SUV, bought a sensible used hybrid on Craigslist, moved close enough to work to walk there every day, and started biking most other places. I now re-fuel so infrequently that, seven months after buying my hybrid, I still forget to hit the "open gas cover" button before I get out to pump.
-Friend of mine's Mom is moving out of state, and he offers me her year-old, self-propelled lawn mower for cheap. He is borderline offended that, rather than accept his generous offer, I decline and choose to continue using my beer-gut propelled reel mower on my half-acre lawn.
-Forgetting to turn heat up when friends and family visit, as my 60 degree "meat locker" elicits shivers and complaints of how "shockingly" cold it is.
-Having to fake happiness when certain friends or family tell me about new car/boat/ATV they are getting, when I know how much they hate their job and how little they have saved for retirement. Inside, I'm screaming "Noooo! You're pissing away your freedom!", but I know a pep-talk about Mustachianism would only be met with staunch incredulity.
-Momentary sadness that all tax-advantaged accounts are now maxed for the year, meaning eight months of taxable account contributions knowing Uncle Sam will take a larger cut.
-When co-worker tells me about the 300 different "favorite" TV shows she has, and having to lie and say "I'll put that one on my list" every time she says "You have to watch it." Seems unproductive to tell her my true feeling, which is: As far as I know, we get one chance at life, so I can't possibly fathom spending hours and hours staring at a TV every day, when there are endless fascinating things in the world to learn, experience, and share. Reminds me of a hilarious scene from American Dad, where Roger is on his death bed and says "My only regret is that I didn't watch more television." :)
