Re: disrespecting to parents
You tie your elder siblings up with a rassi (you may need help)…then you throw them into a rocket…that will take them to the chaand…or preferably Pluto. 
Hmm…all the chotay siblings can talk to the elder sibling about their badtameez behavior in a calm way. The parents also need to talk to the elder sibling and maybe set some boundaries. If this is something that happens a lot…then maybe if the other siblings unite and maintain a distance from the disrespectful sibling…that might wake them up.
