When to use a comma:
* Direct address: If "asked" is followed by a person's name or a noun phrase that directly addresses someone, use a comma.
* Example: "John, did you ask her about the party?"
* Introductory phrase: If "asked" is part of an introductory phrase that comes before the main clause, use a comma.
* Example: "Having asked the question, she waited for his response."
* Interrupting phrase: If "asked" is part of a phrase that interrupts the flow of the sentence, use commas around it.
* Example: "He asked, politely, if she would join him for dinner."
When not to use a comma:
* Direct question: If "asked" is followed by a direct question, do not use a comma.
* Example: "She asked what time the meeting was."
* Simple statement: If "asked" is part of a simple statement without any additional information, do not use a comma.
* Example: "He asked about the weather."
In summary: The use of a comma after "asked" is determined by the sentence structure and whether it is followed by a direct address, an introductory phrase, an interrupting phrase, a direct question, or a simple statement.
