14. They Always Laugh At Your Jokes
It seems like such a simple thing, but a person with a crush will always hear what you say and make an effort to show their appreciation. So, if this potential partner is always responding to you with a laugh or a smile, take note. As matchmaker Bonnie Winston says, "If they giggle at your jokes, that may be a subtle way of flirting."
While not necessarily classic signs of flirting, these little gestures are still the real deal. And they might even mean that nervous, slightly standoffish person is actually totally into you.
