Next time you see him, flirt with him! 😎 Eye contact is great — but as you can see, it’s not getting you anywhere. You need to make small talk with him. Compliment him. Let him know you like him without overdoing it. 😉 Guys like to have something to chase after, and they don’t always know you like them — so by flirting with him, you’re giving him a clue that you’re interested, and you’re also giving him something to chase after.
Let me know if that helps! 🙂
