<human>: My grandma went to Mexico for a little while, and then she started telling lies about my brother and mom.

 She had said my mom was irresponsible and she was a drunk, which she didn't. If she did a have a drink, she would only have one little can of beer since she had me, my sisters, and my brother. To top it off, my grandma ALSO said my brother had down-syndrome just because he had to stay at the hospital for a bit, because he was born a month early. And he didn't have down-syndrome so it was a total lie. Mostly, you could tell by their face if they have a disorder or something, but my brother had the look I had when I was a baby.

My grandma came home and she brought some expensive plates from Mexico and said she loved those plates and that they were precious than humans (crazzyyy!).  A day after my grandma comes, my cousin and I were there because we had to unpack her things for her. Now, my cousin doesn't like my grandma because they never had that kind of bond. Besides, my grandma is a bit self-conceited.

"Do you dare me to break one of these plates?" My cousin asked me with the plate in her hand, the plate five feet away from the floor.

"Dare ya, shes not home anyways. Besides, she told everyone here and Mexico a lie about Eli (brother) and my mom," I said. She dropped the plate while smiling. The glass went everywhere.

We continued to unpack and then we ran outta there before my grandma returned. The next day, we were accused for something we did do.

"Did you guys break my precious, precious plate?! Why did you guys do this?!" she yelled at us, grabbing all the attention from everybody.

"WE DIDN'T DO IT!" We both said it at the same time, with a blank face.

"Oh okay!" she said.

We both smiled and then watched TV. More lies she tells, more plates break. Besides, she has about 100 plates.

Summarize the given text in a few sentences.
<bot>: Grandma tells lie to everyone about mom and my brother, so my cousin and I break one of her precious plates.
