I don't think I can do stories, but I can do the sentence you just gave me uwu
The "h" in "hey" should be capitalized, "can" is correct, but "May" is far more proper, after "see" an "if" should be there to show situational possibility (I think), that "their" is possessive and should be replaced with "there", an "are" should come after the "there" to allow the grammatical mistakes to exist, the "mistake" should have an "s" at the end to make it plural, and punctuation is required to make it a proper sentence uwu
