During the epidemic, I felt very stifled due to the lack of sunlight, as my house is in an alley and blocked by other houses covering the windows. One day, while going to the supermarket, I passed by a plant store and saw some cactus plants named 'birthday cakes,' and I felt a sense of empathy with them for lacking biological sunlight. So, on my birthday, I bought 3 plants and planted them in an old motorcycle seat, something I didn't want to sell and was currently stored at an outside parking lot. Then, every noon, I would walk out of the quarantine area's fence to the parking lot directly opposite, about 200 meters from my house, to bring out the motorcycle and the cacti to sunbathe, and then bring them back under the shelter in the late afternoon. This gave me an excuse and self-hypnosis to create a responsibility for myself to go outside for sunbathing. It was also quite easy since my house is located in two interconnected alleys, only one of which is guarded, and the one I use has no security. This continued until the quarantine fence was removed, and it also made me feel a bit more relaxed and less stifled.
