I wonder If I notice the syntax errors before I post...
If you noticed the syntax errors wouldn't you have fixed them?
Or are you noticing them then wondering about them and while you are distracted your left hand in hopes of bodily domination presses "post" and then frames your right hand so that it can execute the next phase of its plans behind the turned back of your justice system.
The last option is that you might notice them and post that statement so that everybody else would be sucked into your false sense of perplexity.
If the first option fits you, then you are probably like the rest of us careless when it comes to revising. If you chose the third option then you are a very tricky person. If the last option best describes your current situation, then your entire body may in the future be annexed entirely to your left hand.
