May I help you? I know that one BUT I might go to the store? or I may go to the store?"
Readers, I am about to let you in on one of the deep dark secrets of grammar that your English teacher never told you: There's not always a right answer.
It's true! You probably always suspected it, and now you know. The "right" answer depends on whom you ask. I researched this a little, looking in various grammar books and web sites, because I wanted to be sure I give you my best possible answer because I just love you that much. Also because you actually care about this unlike some of the coerced guests in my classroom. So here it is.
|Pay attention, class.|
- Students may read a short story in class tomorrow.
- Tourists might fly to the moon in my lifetime.
Several sources point out that when speaking in the past tense you must use "might have" rather than :may have".
- She might have gone to the principal's office.
I hope you found that useful. If I've left anything unclear please let me know, and I'll attempt to clear it up. Feel free to ask me any of your other English-teacher-type questions. But don't ask me your math questions unless you're a first grader. Just sayin'.
