think to
1. To have an inner monologue; to make a statement to oneself in one's mind, without saying it out loud. I had a moment where I thought to myself, "Why am I even working here?" I'm sure they don't think to themselves, "What if we're the bad guys?" They just don't care.
2. To have the idea to do something. I'm sorry, I didn't think to run the dishwasher before we left.
