Look at someone’s lips to show them you’re interested
We’re not suggesting that you look at someone’s lips for extended periods of time because that will make them uncomfortable. However, looking at them sometimes and letting them know you’re interested is a nice approach to show interest when out on a date.
Touching someone’s hand or arm could feel a bit too direct, so this is perfect for evaluating their interest during a first date. You may be very certain that they feel the same way if you catch them looking back at your lips.
