I try to accept people as they are. All their quirks, style and ways. I know that I'm gonna find litter when I'm out hiking, biking, or camping and try to not let that bother me. People are gonna be selfish and rude and I try to not let that bother me.
One thing that does irk me is when I'm at the gym and there's dumbells, weight plates, water bottles and other things laying around. I find it really irksome to havta pick up after people just to get the equipment and room for a good workout. Didn't their mommy's teach them to pick up their toys when they're done playing with them?
With all that being said, my wife and I recently joined a gym that makes sure that things are organized and clean and I like it.
