Those Days Hidden Behind Red Brick Walls

I find that the older I get, the more I like to reminisce about my childhood moments. I heard that this kind of thing is something that only grandfathers and grandmothers who are too old to walk like to do. I am a little afraid that I am aging prematurely. But the past time was really happy, really, so I want to write it down and let people who read it share it with me; if you also find it very interesting, it proves that I am still normal.
