Always remember to practice your Ki-Blasts safely--that means you shouldn't do it in the middle of a public road, you shouldn't do it near public properties or properties that you do not own, and finally you should always inform the authorities and your neighbors about your Ki-Blasting related activities.
Organize your activities with them if possible. Train when it is most convenient for everyone, to ensure the safety of the public and to make your Ki-Blasting sessions enjoyable and hassle-free.
If your practice sessions are organized, then there is less chance of a random pony walking into your training zone.
The last thing you want is to accidentally Ki-Blast a random bystander or a traveler.
