<human>: Ok, first off, this didn't happen today. This happened a good 10 or 11 years ago, when creamsavers actually still existed. I was around 7 at the time.

Me and a buddy of mine were playing Tekken 3, minding our own business. My sister was sitting on the couch behind us, enjoying a bag of creamsavers. Now, like any wide-eyed kid growing up in the early 2000s, I was unhealthily addicted to video games. To the point where I'd literally blot out anything else going on around me. My friend was the same way. We would never take our eyes off of the screen until we were finished. 

So, this proved extremely bad for my sister, who chose the worst time ever to choke on something. A creamsaver had gone down the wrong pipe, and she was gasping for air before she knew it. Of course, I didn't know this, because I was too immersed in Playstation to acknowledge anything going on behind me. Even when my sister got up, slapped BOTH me and my friend on the back, AND tried to get our attention by reaching for our game controllers, we ignored her. Finally, she did the only thing she could think of- she flung herself onto the couch. Impossibly, the creamsaver came loose and she coughed it out of her mouth. 

I didn't even realize what had happened until my grandmother walked in and pointed out that my sister was crying. Needless to say, I didn't hear the end of it for a long time.

Can you summarize the given text in a few sentences?
<bot>: My sister almost choked to death on a creamsaver because I was too distracted by video games to notice what was going on.
