What minority interests do you have?

My hobby may be very special among my friends ... that is: collecting all kinds of soaps. At a very young age, it may still be the age when I just climbed. Many old people will play a game: put many objects in front of the baby to see which one the baby will pick up and play with. There are about four or five drawers of soap at home now. They are all collected from primary school, and the fragrance of some soaps is still very clear. When I was in primary school, I didn't have much change, so I had to buy some international brands "Nais" ... or a set of five transparent soaps, which are still crystal clear today. When I grow up, when I travel abroad, I will also buy a lot of soap intentionally or unintentionally. Airport duty-free shops have collected many soap gift boxes, and some tourist attractions will also have soaps engraved with wonderful patterns for sale. Take out these soaps from time to time, and ask about the aroma and feelings, and you can go back to the time and scene when you started them ~ Soap is also a good way to retain memories. Most importantly, it is much cheaper than perfume.
