They think they are so high just because they are rich. 

They have no manners at all.

screaming and shouting just because someone give them something they don't want.

When they were teaching me how to fold paper origami, they didn't even explain ANYTHING and when I fold wrongly, they say "NONONONO! Not like that!" 

And if we(me and my sister) don't lend them our iPad and iPhones, they would scream and annoy us and ask why we don't lend them.

Those objects freaking belongs to us.

US.

And they don't even have respect for their elders. 

Shouting at my grandma because my grandma ask them to drink water.

They are only 6 and 8 years old and they behave like that.

What will happen when they are teens?

I'm like ing pissed.

Sorry for ranting.
