Some are debating whether this is a “test” for the reader, but I’m guessing not. The old ‘your’ versus ‘you’re’ is a common grammar misstep, and one that many people will point to when determining intelligence, I would say. Put ‘their/there/they’re’ on that list as well.
So, this, from OkCupid (courtesy of r/okcupid), a dating profile stating specifically that proper use of ‘your/you’re’ is essential if you are to message her — followed immediately by breaking said rule.
TIP: Grammar can make or break your profile. Spend a second and paste your profile text into Microsoft Word and see what gets flagged.
