Wow! Mr Paul the grammarian, I would simply say here that you "really know it, and you are really here for it!"
At first, I was thinking (if I could be given the right answer) over the topic I gave to this question, not that I made a mistake calling it "tense" but knowing that the real topic should be "bare infinitive". I did this just to know if my teacher knows what's teaching us. Your answer gives me more confidence in you and your website even by simply mentioning that word "bare infinitival". This made me know that you really understood the question.
Your site is really the "GRAMMAR MONSTER". And coming across a site like this is really awesome. Thanks for bringing clarity to this.
