I actually have autocorrect turned off for this various reason... LOL I haven't used it in YEARS. It used to autocorrect things to the wrong thing all the time!
The *ONE* I remember, I was chatting with a friend and I typed something like "Talk to you later, chica!" And it changed it to "Talk to you later, Chicago!"
The part I DEFINITELY know happened was it changing chica to Chicago. I just can't remember the exact verbiage of the conversation. That was SEVERAL years ago. Around a decade or so, ago.
