I feel tiny and ridiculous next to her. We went on vacation together, and I was hoping she'd finally like me, but I'm a head shorter than her. And for the past three days, all she's posted on her stories are pictures of huge surfers who are a good two heads taller than me... Every time she looks down to talk to me, I just want to disappear into the sand.

Take a deep breath: a few centimeters shorter have never ruined a relationship, but the poison of Instagram has. What you see scrolling through her profile is beach folklore, not an NBA tryout. Sun-kissed giants make nice photo props, but posing next to a guy says absolutely nothing about how she feels about him. On the other hand, the real vacation romance killer isn't your height: it's the energy of a guy who hangs his head, broods, and feels defeated before he even starts. To turn things around, get out of this toxic comparison. Take her out for a drink, just the two of you, make her laugh, and be upfront with self-deprecating humor if the topic comes up: "I may not be six feet tall, but at least I fit perfectly in the photo frame." Charisma isn't bought with a tape measure—straighten your shoulders, the sand is the same for everyone.
