Dating is a tricky thing. We’re always trying to tell the difference between creeps and actual prospects. But even if you’re the nicest girl or guy in the world, there are a few mistakes you can make that will have your date running in the opposite direction before you can even ask if they want dessert. Here are 10 surefire ways to scare off your date.

Know their address before they tell you

Maybe they happen to live in your friend’s building, or maybe you coincidentally saw them walking up to their house one time. But if you reveal that you know exactly where to find them before they’ve volunteered the information, you’ve just labeled yourself a stalker in the extreme.

Reveal your extensive knowledge about their life, thanks to Google

Again, showing that you’ve done your background research isn’t always a good thing. If you can come up with your date’s family tree, school record, and history of achievement in high school sports (seriously, Google, how do you do it??), expect them to run, and run fast.

Continually reassure them that you don’t have a criminal record

Me thinks the man doth protest too much. It’s the kind of situation where, if you keep bringing it up, you’re going to arouse suspicion. Telling somebody, “Don’t worry, I definitely won’t kidnap you,” makes the only thought in their head about you kidnapping them.

Tell seemingly hilarious revenge stories about your exes

Your friends may have thought it was funny as hell when you dumped out your ex-boyfriend’s closet and lit his clothes on fire, but all your date hears is pyromaniac tendencies and a penchant for revenge violence. They are most definitely looking for the exit.

A complete lack of awareness when it comes to personal space

It’s nice to get close, but then there’s too close. Even if it just means that you’re breathing your coffee breath all over their face, or, even worse, spitting, your date is most definitely looking for any room to budge over and escape.

Inviting your friends to “casually” show up

What are the chances that three of your friends just so happen to show up to the same coffee shop, in a city that has about two million coffee shops, when you’re on a first date? Very small, I think. It means you’re trying to get them to scope things out for you, or planning an elaborate kidnapping plot (there’s a chance I harbor many fears about being kidnapped…).

Too many compliments

There really is too much of a good thing, and when you start complimenting her shoes, then her pants, then her shirt, then her earrings… you get the point. It’s nice, but there’s only so many times she can say, “Oh thanks, I borrowed it from my roommate.” Because really, who wears their own clothes on a first date?

Insist on walking them home, when they really insist otherwise

“No” means “no,” buddy. If they don’t want you to walk them home, most likely to avoid giving you their address or the awkwardness of the goodbye kiss, let it go. It ain’t gonna happen.

Showing up like this

Just…no.
