Maybe you can make a guest list and if they show up the won't be allowed in
Tell your parents about these individuals and that they aren't welcome to your party. If need be, let the parents check the guest list as everyone arrives. That way, no one uninvited shows up.
Tell your dad that theres these guys you don't like and that they weren't invited, but you think they might show up. If they do, he can ask them to leave. thats what i did and it worked
me anda friend have been planning this joint 16th party and i think it could be really good, like we have similar friends, my house would work really well, and me and her both want to do it.
we would deal with everything fine, but i had a falling out with two guys a couple of months ago and im afraid they might try and crash..
what can i do to prevent them crashing!!
thanks
