This question already has an answer here:
I can't figure out for the life of me if it should be "should's" or "shoulds."
It's a follow up sentence of saying, "that's a lot of should's."
(there was also question as to whether the period should go inside or outside of the quotation mark after should's)
I looked over the link of Is "’s ” ever correct for pluralization? but still couldn't figure out what the solution would be to my question. Being more direct of whether it should be should's or shoulds would be more helpful, thanks!
