step 1. Hold a tryout, (e.g, movie tryouts, friend tryouts)
step 2. Tell everyone that this tryout is top secret and that you need to do it in the barn. Wait till everyone is in your barn, then click home options (in the top right corner.)
step 3. When you click home options, it should come up with a list. Everyone, Buddies only and nobody. Click nobody!
step 4. Enter your barn and say, "nvm, just come back to my house" When they try to exit, they won't be able!
Have fun! xD
