My mom "grounded" us "forever" all the time, and often for the most trivial reasons--didn't clean up the kitchen to her standards, kissed a boy at age 16, got a C on a report card. Basically, anything that she felt made her lose face with the neighbors.
On the other hand, she forgot the punishment quickly and we knew if we could just lay low for a couple days the whole thing would blow over.
Grounding never did a thing for me because it had no teeth. I have grounded my children for major infractions--shoplifting, looking at porn on the internet

, treating me without respect, making Fs on a report card. However, I chose a reasonable discipline and wrote it down so I wouldn't give in early. Shoplifting? Dad accompanies you to the mall where you deliver a verbal and written apology, return the merchandise and take the consequences. No outings for 2 weeks. May go to the mall accompanied by parent, not friends. Porn? lost PC privileges for 6 months and had to earn it back one week at a time. Fs? Lost cell, video games, and PC until grades were above a D. Earnd electronics back one at a time until grade is above a C. Disrespect? Lose all electronics, visits with friends, telephone calls, and weekend activities.
My kind of grounding works.
