Question of the Day: What is most important element when you're on a first date?

Poor grammar can mean the difference between a first and second date. A survey from the dating website, Plenty of Fish, finds good conversation and grammar can make or break a couple's chemistry.

Over 2,000 singles were surveyed and 74 percent agreed that good conversation is the best indicator of attraction -- even more so than physical chemistry.

More than 80 percent find great conversations on a dating app lead to equally stimulating talks in real life.

But poor grammar will ruin the chemistry altogether.

Users agree confusing "their" and "they are" is worse than other negative things in relationships.
