Have you ever forgotten what was pissing you off?

Yes, this is the start of the amazing period of time in which people actually comment.
Seriously, I'm only warning about troll wars, besides that, some commenting with problems or whatever would be just totes legit dude. (Catching that whiff? It's sarcasm.)
I really would like to read what people have to share, its always been pretty cool to know you're not all robots or me refreshing the page too much.
Back to the title:
Yesterday, I was pretty pissed off. It was a bad day. Up til lunch, I was constantly this close to punching someone in the dick, boob, or throat.
I was walking to my next class out of lunch, listening to my angst playlist (yes I actually named it "angst music") when suddenly some person I don't even know grabs my hand and walks with me.
Now I was pretty weirded out, but some little masochistic voice inside my head told me to just be cool and play along.
So I smiled and we started talking about history class until we got to the hallway and they turn and say
"Thanks, here's my class. See you later." And walk into class like whatever.
Meanwhile I literally have no idea what their name is. It's like when you rp with someone on omegle and then the connection dies at the worst shitting moment,  and you never meet again.
But I only realized later that I couldnt remember why I was so pissed in the first place. I was giggles and shits the rest of the day.
I really, really want to thank them. Creepy as it all is, they actually helped me out. And that's cool.
Now I'm not recommending that you go and grab someones fucking hand and start talking to them like old buddies, but, if you see someone being a little Bitch about life and trudging down the hallway with breaking benjamen blasting in their ears and broadcasting a general aura of doom, do something nice. Maybe even a smile. Anything can help.
Off of the dramatic shit, question of the post:
Has something this weird ever happened to you? Or have you ever just suddenly forgetten what you were bitching about in the first place?
I look forward to hearing your
TOTAL BULLSHIT
