Well. There you have it. This is what happens when you try and share your Eden. Be warned. Children are evil and should have been chucked out of the garden along with the first offending couple.
Time and again it is proven to me that everyone's idea of the perfect Eden is very different. I guess the only protection is to interview all potential sharers of the space very carefully to see if their Edenish views correspond with one's own.
Question 1: Are you likely to want to introduce some God-awful big clunky red metal thing into my Eden? Answer: Yes. Out you go then.
Question 2: Are you going to cut beautiful vines off the ugly fence? Answer: yes. Well stay on your side then, ya Cretin.
You get the picture.
