I'm probably not going to jump anyway, but it's nice out here.
Uh...okay. Once you've enjoyed the view for long enough, just jump down into a bush or something. You've gone too far to stop now!
If you manage to get down, just ring the doorbell. If your parents get really mad about seeing you outdoors in your birthday suit, a simple explenation is always necessary.
Don't forget to tell them I helped you!
