Input: Text: like most people's fuck ups, this was years ago.  i was at a bar (where it's half dedicated bar with a doorway to another larger dance room with another bar) with a buddy. his gf shows up along with her friends.  score!  i'm really hitting it off with one - we're talking, flirting, etc sitting kind of near the end of the bar.

now we're decently drunk - i can't remember what we were talking about, but her keys were sitting in front of her near her phone - i grabbed them and was looking at a cool keychain from europe or something she had and i was asking her about it, as she finishes that story, i'm like "oh what about this?"  fucking hair trigger mace keychain.  i spray her right in the side of the face, like lloyd christmas with binanca...

she freaks and holds her face while running to the bathroom.  a couple friends accompany her and i'm still sitting there with her keys like.... wtf just happened.... a moment later i went to say i'm sorry 1000x and she's surprisingly cool about it.  half of her face is just beat red, eye is watering nonstop, its bad.

i head back to the bar and everyone is outside of the bar in the hallway (it's like a strip mall brewery type place in duluth, mn) and doors to the bar are closed off and doors inside for the dance floor closed too.  i ask some random, whats going on?  "some asshole sprayed mace or something and it's floating around burning everyone's eyes!"  i just say "oh. what a dick.."  and turn to check on her again.  

she was sober enough to drive at this point - we even stopped to get mcdonald's (i bought!) and pulls up to my apt - "are you ok to drive? want to come in?"  she says "i had planned to, but i should probably head home to take care of my face".  told her she still looked beautiful, but a kiss is all i got.
Output:
TIFU - Maced a girl at the bar
