I gave it somewhere in the universe. Preponcha (P) begins to ask my classmate (O):
Q: How old are you?
A is twenty.
Q: In a few years, your parents will get old and start to suffer from terrible diseases. You will have to give them injections. So tell me how much to boil the syringe before the injection?

Q: The answer is wrong. Your parents are dead.
A: But I can buy single-use syringes!
Q: Boy, what is written in your note? The archivist historian. You never, you hear, will NEVER have money for a single-use syringe. Learn before it is too late.
