I find it fascinating when lives grow. You can see a little leaf growing out of the concrete or a beautiful bouquet of flowers striving towards the sky. I pay attention when I take strolls. I look at the houses imagining what it would be like to live there and how would that place be affected once we would let nature take over bit. You can fill a street with concrete and see greeneries interfering, you can leave the trash bags outside and see the raindrops or leaves falling on them.
