The power of habit.

Somewhere a month ago in the country, he repaired a garden cart and put the old wheel to the house. I walked past here, I watched, and under him the hamsters were flying. I decided to look, moved a little to the side and found a crack in the foundation, in which these same hamsters built a nest. They are no longer useful insects. Well, the roof did not return to the place, so as not to prevent the tenants from getting home.
After a couple of hours I look, and already a few hamsters on the concrete crawl around the edge and do not climb into the nest. I decided to observe. It turns out that the hamsters are still flying under the edge and trying to find the entrance to their house there, knocking their heads into a deaf concrete wall. The fact that the desired gap is 10 centimeters to the left, they do not care - it is supposed to go under the edge, and the point!!! to
I had to bring the roof back to place. Immediately the house was found, and the insects calmed down.
