Write a condescending Reddit post in which a user chastises another user for not knowing the difference between "they're", "there", and "their" while they themselves constantly mix up "your" and "you're".

You're intelligence must be quite low if you can not even get that much right. You're stupid. Just admit it. That's what your, stupid.
