Snakes are just a very common reptile and a totem relic of some ethnic groups. As one of the 12 Zodiacs, legend is the incarnation of dragon. But because of their concealment, toxicity and aggression, people are afraid of them. So your parents will feel scared when they see snakes and think something may happen. I suggest you don't take your parents' words to heart, which will only increase your troubles and fears. Of course, you need to be careful in everything you do. Can't you see there are warnings everywhere in the mall? Slide carefully and meet carefully.
Are snakes different from horses, sheep, monkeys, chickens and dogs? According to your parents' logic, are those people not allowed to go out?
So your parents' worries are unnecessary.
