These pictures are from few months ago. They show bridges and train station along a wooden train tracks. I let my kid play by himself for longer time then usually. Until then I didn't know I can get such achievements from him just by letting him be by himself. Until then I had an idea that I should spent my free time with him as much as I could. But apparently it is not like that. He can immerse in his little kind of unstructured playing while I am sitting on the sofa staring out of the window, thinking about the "immortality of a beetle."
