Well, if it's you first time, point out that you've never been to one before and would like to try it out. You could also try to find out what activities you are going to do from the person that is hosting the sleepover and list them out to your parents, to make them realize all the fun you might miss. It took me awhile to convince my parents for a first sleepover also, but now they say "Yes" without even thinking.
I really don't think you should let them. They are her parents let them do their job. Maybe you should start with a playdate. Let them grow to it. To them that's their little girl.
Just ask, if she/he says no then ask why. If you haven't done your chores or homework for the weekend that maybe why. Tell them that you will be very well behaved unless its at your house. Ask them if they know the friend. I hope i helped!
Well I say convince your parents that you are mature enough to have a bigger space. But if that doesnt work invite only a few friends!
You can tell your parents you have to go and study with them and then they will say yes to having a sleepover.
Well, you should invite your friend and her parent to church with you. You'll take your church clothes to your friend's house. You sleepover and when it's time to go to church the next day you guys get ready like you normally would. Then you meet your parents at church. whoo-ooh!!!!!
Be nice to your parents.
You don't.
You cant convince your parent's because they have a good IQ your parents not be tricked by anyone.
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.
