Sometimes does your autism just come out?

I spoke to my wife last night on the phone, I’m working away at the moment. The call was just the normal of how our day had gone. All of a sudden I said, “ I’m going now, I’m bored.” The call ended shortly afterwards. 
I rang her back this morning and explained that I wasn’t bored with her. She was okay about it, her reply was,” anyone would think you have no filters fitted!” I think she knows me by now, sometimes what I’m thinking just verbally comes out.
