<human>: Today was my gramma's 72nd birthday so our family had a little get together to celebrate. Now at these parties we split up the family into two tables: one for the younger generation of Asian Americans and the other one for the older generation of immigrants. As a result, the younger generation tends to stay together and not meddle in the business of the other table.

About halfway through the party, everyone's having a good time when one of my distant aunts comes to our table and starts talking to us. She starts scolding and ridiculing us for not "respecting our elders" since no one has acknowledged our grandmother's birthday yet. Having put up with enough of the criticism, I, being the sarcastic jokester that I am, go over to the other table, kneel down on my knees, and start bashing my forehead into the floor, giving my grandma a traditional kowtow.

Immediately, the whole family starts throwing fits. Picking me up from the ground and shoving me back towards the other side of the room. Being a seventeen year old guy, I'm downright kind of embarrassed so I remain quiet for the rest of the night.

On my way home, my parents start yelling at me once again in the car. So I question what the fuss is all about since I've learned in my global history class that the kowtow is a symbol of respect to the highest power. However my mom explained to me that the kowtow had a whole 'nother meaning from their province of China. As it turns out, the kowtow is only used in their little province to worship the dead. Therefore, I wasn't showing any signs of respect to my gramma, but wishing her death... ON HER BIRTHDAY.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: kowtowed to my gramma as a sign of irony, turned out i was cursing her with death on her birthday.
