Kids trespass all the dam time, it's not malicious. It's kids being kids. Most times they don't even think about it. Kids occasionally run through yards while playing or taking a short cut.
Hell even adults some time need to trespass. A while back, while I was walking my dog, he wiggled out of his leash, and just took off. I ran after him. He crossed the road and went into the yard of other people. I chased after him, and in the process I was trespassing. No one came out and started yelling at me or shooting. No one called the cops. Cause people here are reasonable and not a bunch of mentally stunted misfits.
