<human>: So to start with this is my first post so I'm sorry for any mistakes but here we go...

First I'll set the scene, I'm in high school on my schools weight lifting team, and I generally hang out with some buddies in the front of the school after practice. We joke around, act like dumbasses, you know the usual. Also I am a very nice guy who never intentially hurts someone's feelings (important later).

Now for the fuck up. So I'm sitting with my buddy after practice waiting to get picked up when he gets a face time from his brother saying that him and his dad are on the way to pick my buddy up. I look over to see his brothers face at a weird angle and for some reason my dumb ass brain blurts, "why is he making that retarded face?" (Meaning why does he look different, I have no idea why it came out the way did). My friend looks at me and says, "He has down syndrome asshole." Then I hear I sort of moan coming from his phone. I look down to see his brother crying. I made a kid with down syndrome cry. Being the nice guy that I am I had no idea what to do, I had never made someone cry in my life. At this point my friend is pretty mad and cursing me out and his dad was hearing it all and from what I heard was also pissed. So I pretend to get a call from my ride and slowly back away, proceed to trip on the bench, fall on my ass, get up and sprint away to the nearby taco bell. Where I then order a quesorito to help myself feel better. I'm still cringing while I type this at my house. My face has never gotten that red.

Can you give me the gist of the text in a nutshell?
<bot>: Said my friend's little brother's face looked retarded, found out said brother has down syndrome, pissed off the whole family, got a guilt burrito at taco bell.
