I often mix up two games if I've been playing one for a crazy long time. I've dropped OR for now, but I'll probably get back into it whenever the next one is close to being released. That's what happened with my Y version as well.
Sometimes I will get on to breed specific things for others though.
I've had almost the opposite problem, I start to run in pokemon but stop myself because I'm worried about trampling the grass before remembering which game I'm playing lol.
A bit over a week ago on Friday I had finally got a shiny hawlucha after trying forever to Masuda/IV breed one. Shortly after I started IV breeding a honedge and got a shiny on about the eighth egg, wasn't even Masuda'ing but after I got that hawlucha I had the best luck with shinys so I see her as my good luck charm now.
Haha even the best of us do this from time to time! But hey a bike would be an awesome addition to the next Animal Crossing game. Just imagine zooming around your town on a cute bike. ^.^
