5. Winking
Here’s one of those things that some people seem able to pull off and maybe even make it look cool, while others who attempt it end up looking like creepy. That’s one reason why winking can be a bit risky and winking like someone who has something stuck in their eye could send potential romantic interests screaming in the opposite direction. Unless you are one of those people who can pull off the wink and look cool in the process, you are better off relying on eye contact and a smile to show someone that you are interested.
