Thing is, speaking for myself, I'm literally surrounded by lots of other stuff (your birds and trees for a start off) and their proximity doesn't make me obsess about them.
Plus, plenty of folk manage not to obsess about alcohol and they're surrounded by the same things.
It comes down to the fact that I'm alcoholic, and if I didn't see a single ad in my first few months I'd still have obsessed over it. Thankfully working a solid program of recovery helped rid me if the obsession, and as long as I keep doing my simple daily maintainence work I believe i can keep it at bay.
