Doctor: Because your sexes and species are both unusual, the safest and most efficient way for you to have a child of your own is to create one in a gestation pod. Of course, in theory, it is possible for an interstellar human A to conceive the offspring of a male insect.
Male Insect: Tell us the odds.
Doctor: If the two of you succeed, the odds are 0.75 out of the total population of all intelligent life in the interstellar world.
A: And what does the other 0.75 refer to?
Doctor: General Mo Che and his A partner. But General Mo Che isn't a pure-blooded insect, so we can only count him as 0.75.
Male Insect: All right. I'll do my best to follow General Mo Che's example.
A: Keep it up. I believe in you.
Doctor: If you manage to conceive, please be sure to let me conduct the research.
Ten years later.
The two went to the hospital for a checkup and contacted the doctor as promised.
Doctor: Tell me, how have you two managed this for so many years?
Male Insect: Keep buying lottery tickets and building up the odds.
A: Eventually, we'll get lucky.
Doctor: ...How many times?
A: I've lost count. At least X times every day for the past ten years.
The doctor looked at the male insect with respect.
Doctor: So why didn't you use a gestation pod? If you had, your kid would already be in elementary school.
A and Male Insect, in unison: We couldn't afford it.
Then the male insect said: Doctor, given how unusual our situation is, could you charge us a little less?
A said: Mostly, we want to raise the child properly. If we lose it, you won't have anything to study, either.
Doctor: ...No problem. You can move right into a luxury private room for one-tenth the price.
This is the love story of two broke guys.
Theme: Even in adversity, you must keep striving to improve.
