How to politely ask parents for money?

Ask your parents politely for money. You can use this method:

If he has been a soldier and has common sense of military life, tell him: Dad, I want to launch a new wave of charge. At present, ammunition and food are used up, requesting fire support from the chief. He'll be happy. He'll give you a "cherish the bullet" at most, and the money will soon be available.

If parents like humor, send them a message saying, "It's good to have a job and income, and you won't be so cash-strapped as you are today." They will know that you are short of money.

If parents need to make it simple and clear in order to understand, they can say: Mom and Dad, if you have spare money, please give me some money.

Our parents owe us nothing. Asking them for money is actually asking them for help. We have no reason not to respect those who help us. It is natural to put it mildly and listen moderately.
