How Can I Convince My Mom ?

Hey, I don`t now if this will help but you could:
Tell her that they can sleep in a different room,
Tell her that they can sleep in your moms room on the floor.
Or you can tell her that she can stay up untill you ALL fall asleep. Or you could also tell her that when you people go to bed thern if she hears one noice then you`ll be grounded, or if you have a little sister or brother tell your mom that they can watch you guys.
Hope this helps . Oh one more thing, this is what i told my mom and it worked. Tell your mom or dad or whoever is in charge that if they let you have boys spend the night that it will only be something that happens once a year at the most.
Hope that one helps, sorry if it doesn`t.
