Just make sure the people that you invite aren't the kinds of people who rough house and your parents don't have anything planned for that night
You can tell your parents you have to go and study with them and then they will say yes to having a sleepover.
When both of you'll agree to it. Tell the parents also
"Flaming Moe's" (season 3, episode 10) started with Lisa having a sleepover.
Be nice to your parents.
You don't.
sweet talk them and sound mature!
Hope
First you have to be invited by the person who is hosting the sleepover. Once you have been invited you should ask your parents for permission to attend. It is then their decision as to whether you attend or not.
You should have your sleepover in the living room or the basement, somewhere where there is lots of room. It should be far away from your parents so you can stay up late! :)
Don't be too upset, it may be that your friend's parents are the ones who don't want sleepovers.
You just beg them
The proper time to pick a child up from a sleepover is whenever is convenient for the parents hosting your child at the sleepover. Every family is different, there is no certain time that works for every sleepover. If they don't really care what time, go with whenever is convenient for you.
