What's wrong with pinching your fingers?

I tried to count my fingers, but I found my fingers numb. Let's take a rain check! Tell me what it says.

I tried to count my fingers, but I found my fingers numb. Let's take a rain check. Let's talk about what this means. The author doesn't really want to pinch his fingers to tell fortune, but tries to shirk the matter under the pretext of numbness of his fingers and express his unwillingness or unwillingness to do something. This sentence is a joke, borrowing the metaphor of pinching fingers to tell fortune, and conveying the author's attitude of not wanting to do something. Among them, "pinching fingers to tell fortune" refers to predicting people's fate through the change of fingers, which is a superstitious behavior. The author begins with "I want to pinch my fingers to calculate", which obviously implies that I have a plan to do something, but in the end, I use "my fingers are numb" to get rid of this plan, forming a joke effect. At the same time, this sentence also uses the mantra of "another day", which means that you don't want to or don't want to do something, but you don't want to refuse it directly, hoping to postpone it to some time in the future. Generally speaking, this sentence conveys the author's relaxed and humorous attitude and shows an optimistic attitude towards life.
