Am I the only having trouble here?

Can you tell me more about this?
When typing the auto fill doesn't act like it does on other sites or while texting. I know auto fill gets to know the user and frequently used words or phrases. On here it seems to pick words at random, and as one guy mentioned earlier apostrophes give it fits. It's not a big deal. I just have to proof read everything a few times as I'll find wrong words, garbled sentences, repeated sentences, and other bizarre things. It's like a confused drunk using voice to text.
