Should I tell my partner there are 28 days in February?
Why did you want to tell him that when there are some years that are leap years?
I want to confuse him.
It is good to share what you know with others but you have to make sure that you are giving them all the information. Otherwise they will be confused and blame you when they tell others and get corrected.
I'm smarter than you.
I don't know, that may be true, but it's not something you should brag about. If you tend to remind people that they're not as smart as you they'll start avoiding you. It's okay to help people when they need information, but you shouldn't make them feel dumb.
